Im looking to upgrade some gear and i think i know the response im gonna get but throwing it out there. I want to get some version of knee sliders so i can practice up on turns/lean. This may be a big parking lot in spare time or future track days. So two piece sounds like a nice option, looks like the track day providers i would use are cool with that. Personally i have zero experience with them, functionality or anything. I have very little experience in a once piece, but i do know i would feel a bit strange fully kitted up in a technical college parking lot doin some low speed sloppy turns. The other option would be the least safe but still an option for at least some spare time training. Not sure if they exist anymore but icon clover leaf velcro knee sliders. Lets hear it!
