WHAT is the deal with flip flop wheels??
Do any of you ride combo wheel shapes, I.E. asymmetrical ones like Santa Cruz Vomits or OJ Mini combos?
If yes, which way do you use them, and why?
Like, conical side facing inwards for better lock-in on grinds, or rounded side inwards for hanging up less?
Which way do the pros run theirs?
Also most of my local skateparks are plywood, Masonite and skatelite. Think kinda slippery dusty stuff, and I have a fear of slipping out, which duro should I get?
OJs only come in 101a and except for the Gregson 56mm 97a. Slime Balls come in 97 and 99, right?
Currently on Spit F4 57mm Radials in 99a. I haven’t really given them the full test yet, because time. Some people claim them to be very slippery, and others perfect, what’s the verdict?
I had meant to reply to this a while back but got distracted.
At least you pretty much have the info re asymmetric shaped wheels, but some people do like to ride them in and some out, most the normal way, as said, but they do give you the option, mini combo = a combination of two wheel shapes so you can choose either way depending on what you want or how wide your wheel to truck to deck is and other factors.
As for the surfaces of different ramps, as well as how people skate, there can be so many variables between what might be considered the best wheels for any given place. Some people like to have that slip and slide feel, whereas others prefer NO slide unless they want it to slide, so you can easily go from 101 / 99 down to 90 duro and everything in between for the same ramp, depending on who is skating it and what they prefer.
Try the normal wheels you have (with caution) and if they are extremely slippery, then I would say go down to a lower duro than 97, but if you just wanted a touch more grip, then the 97s should be good.
The different wheel brands with different formulas will skate differently as well, but for the most part the 97s from Spitfire and Slimeballs will work well on moderately slippery ramps, but will still feel too hard on very slippery ramp surfaces.
Lower duros than that I found that the Mini Logo 95 duro or even the 90 duro were really good, kept speed and didn't slip out on the skatelite / slippery wood / other surfaces around here, whereas some other 95 duro wheels didn't keep grip on the slippery stuff and some other 90 duro wheels just ended up being very slow to roll over those surfaces, when compared to the normal harder wheels.
