The interesting/challenging aspect of all this is that the more I skate the X99s, the harder it's gonna be to switch back to "normal" hard wheels.
Ramble ahead...
Been on x99s for a while now (jumped back on 99a spits a couple of sessions then back to x99), no park, just street; this past week I've been on STF 103a V3s aaaaaand, the speed and slide is sooo good, so predictable, pinch grinds are so much less effort, less sticky and bluntslides are on point...yes it's a bit chattery and my legs/knees do feel it but I think I'd rather perform better for a short time than skate longer with less-optimal performance AT spots that don't
need the x99s, or 99a spits (which for me are a distant 3rd now (stf/f4 tie > x99 > 99a spits > x97s).
Went back to 99a spits and couldn't do it they just felt sluggish (these were old tablets...same feel with my old conicals), switched right back to 103s on the spot. Now obviously any 99a is going to feel slower/less slick, but I'm def spoiled by the liveliness of the x99s compared to any 99a...x97s just feel like cruiser wheels now. I have a recent drop/'set of 99a lock-ins that i skated a few times that are VERY white and felt way, way harder than the other two sets of [old] 99a spits...do 99a spits just drop off at some point that I don't remember?
Going to go back to 101s - maybe spit classics or conicals since finding real stfs not x-form, is proving very difficult, and my stfs are all below 50mm now...but I honestly don't remember how 101a f4s feel (compared to STFs) the last time I rode 101 spits was my last set of radial slims...so well over a year.
