To dismiss the Marsblade ability to provide a "rocker-like" feel for inline skating is baffling to me but then again, I probably do way more ice skating vs. inline skating compared to almost everyone here haha. I only play inline once a week while between playing on two ice hockey teams, playing Shinny at least once a week, and officiating x-1x games a week, the transition from ice to inline improved dramatic when I first used the O1 and continued with my current setup of R1. If you think that using a normal inline chassis is the same using the O1/R1, that tells me that either you don't skate on the ice on a regular basis and/or your Marsblade chassis is setup in a way that it practically has no "rocker" while one is using it for playing/training.
