- The goal is to find what Degros refers to as a Goldilocks zone: A wider wheelbase paired with a shorter wheelbase truck, or shorter wheelbase paired with a wider wheelbase truck.
Good post by OP. But neither OP nor Ben Degros understands wheelbase. Hear me out.
The main issue is that they both assume there is such thing as a "wider" or "shorter" wheelbase without actually measuring any TOTAL wheelbases or understanding what wheelbase they like. More on that in a bit. 15" board wheelbase? Oh, that's "long," I need to put Aces on that. Wait, everyone needs to do that and that board will magically work for them? What determines how long the board needs to be before Ventures don't work? Or how short before Aces don't work?

What is wheelbase?My not-so-outlandish theory: the wheelbase that actually matters is the TOTAL wheelbase
axle-to-axle, like a car.
No one--outside of the Truck Wheelbase thread--ever measures this. If this is consistent, you will have a relatively consistent feel in rotational leverage. If this is random, every board is going to perform differently in tricks where wheelbase matters.
There is no point in pairing a "short wheelbase board" with a "long wheelbase truck" if what your body desires is, for example, a 17" wheelbase axle-to-axle, but you're just randomly trying to hit it with this "Goldilocks Zone" notion, rather than actually measuring your preferred wheelbase and reproducing it. A wheelbase of 17" is always going to rotate the same, regardless of board/truck pairing.
The axle-to-axle wheelbase of my current setup is 16 5/8". If I decide on a new Christmas complete, I can make the rotational characteristics almost the same as the current setup--regardless of board wheelbase, regardless of truck brand--if I just make the axle-to-axle wheelbase 16 5/8". Simple as that. I could hit this mark with Aces or with Ventures; I just need the appropriate board pairing. To hit a 16 5/8" axle-to-axle wheelbase with Ventures, I'd need a ~13.5" wheelbase board. My experiments suggest this board would perform roughly the same as a ~14" with Aces--at least in the areas that wheelbase most affects. The "Goldilocks" model attempts to replicate these findings while skipping the truly important measurement: axle-to-axle wheelbase.

Why it mattersI believe axle-to-axle wheelbase relates to
shoulder width. Like sport jacket size. When I put my skateboard with 16 5/8" axle-to-axle wheelbase up to my chest, the wheels are just past the ends of my shoulders. My preferred axle-to-axle wheelbase IS my shoulder width, give or take. It's no coincidence.
Yes, wheelbase affects how your trucks turn and it affects pop, but it MOST matters when you're doing a trick where
rotational leverage is the main driver of the trick. Eg kickturns, 180s/360s, and shuvs. A back 180 on a 16 5/8" wheelbase always takes me less rotational energy to execute than a back 180 on a 16 6/8" wheelbase, regardless of different pop characteristics, weight, and other sources of leverage. Shuvs are slower when my axle-to-axle wheelbase is longer--just as flips are slower when the board is wider. I can even feel an 1/8" difference just doing kickturns on transition. It absolutely affects kickturns, 180s, and shuvs more than any other dimension of the board. And it obviously affects your stability and foot placement for every little thing, particularly on transition. I mean, it's hilarious people here obsess about how the amount of washers on the inside of your hangar affects flip speed, or whether spacers add weight to your setup--but no one even considers how much an 1/8" different wheelbase affects every single rotational maneuver you do. Jsoy is the only poster I've seen that has related wheelbase to shoulder width in the Gear forum. But I don't think he's ever noted the importance of TOTAL (axle-to-axle) wheelbase.
This is only part of the puzzle. But my theory actually addresses
wheelbase-to-body ratio, rather than the wishy-washy "sub-14.5" boards should go with Ventures, over-14.5" should go with Aces--it's just Goldilocks logic" nonsense that Ben pushes. How does that even make sense? We aren't all the same size. Ben is literally twice my weight, and his shoulders have to be a good 3" broader. His stance and physical leverage in turning and rotational tricks have to be at least that 3" different.
Why even posit the very important revelation that our boards should relate to body size, and apply it to deck width vs. shoe size and deck length vs. inseam (both of which are correct) if we're going to stop short of wheelbase vs shoulder width, and instead prescribe "Goldilocks" deck/truck combos?
I mean the inconsistency is just weird.
My measurements:
5'5", 115 lb, size 7 US men's foot, 28" inseam, 36S jacket
Currently on an Enjoi with Ace 22s, which measures:
31" length (about the length of my leg, from foot to hip bone)
16 5/8" axle-to-axle (about the width of my shoulders)
7.75" width (about the size of my foot, from ball to heel)

What wheelbase isn'tWill this make Ventures turn like Aces, just by putting one pair on a 13.5" board and the other pair on a 14"? No. Actual turning characteristics will vary somewhat depending on truck geometry, whether I have the bushings right, width of the board/truck, and wheel shape (affecting leverage). And pop characteristics? Well, as OP's post points out in various ways, pop characteristics are dependent on basically every measurement: particularly fingers of flat/truck combo, but also height, wheelbase, weight, and even--in the case of flipping and rotating--wheel contact patch and their placements in relation to the board concave. That is going to require another post to address. Part of my point is that
picking wheelbase based on pop characteristics or turn characteristics is muddying the issue. Pop and turn are both dependent on many interrelated things.
I think the best thing to do is sort your correct width, length, and wheelbase first, and then experiment with pop. Pop relates mostly to how high the board rises when you stand on the tail (what Schmitt calls the "triangle"), how light that feels, and where the fulcrum is in relation to your body. How high and heavy the board needs to pop, and where that fulcrum needs to be, is--surprise--different for different people, tricks, and terrain. It's not just: oh, there's three fingers of flat, Ben says to use Ventures. C'mon.
I just feel like if we're going to try to think critically, let's at least TRY to think critically.

TL;DR: OP is on the right track, but he's only scratching the surface. Less YouTube, more measuring tape would help. I'm not a huge fan of Ben Degros. What he talks about are merely starting points to help make different setups begin to feel the same as each other--without having to understanding why or to use a ruler. And that's a good place to start if you don't want to think too much. But this is the Slap gear forum. We want to overthink, don't we?
I recognize this is an AGGRESSIVELY kooky first post. I apologize for nothing.
