new wheels problem, too much grip, any fixes?

Hi, I play on sport court, and it seems I can´t find proper wheels . I originally played with the millenniums "x-soft" that came with my skates, and I was not able to do a proper hockey stop, I thought that I was too heavy for the wheel hardness (im 190 lbs) , so I tried putting some 80As  in the 2 middle wheels,  that was a bit better, but felt like too slippery for turning or accelerating, and still a bit hard to stop . I decided to change them for the "soft" millenniums, and they still felt like too much grip, they wont smoothly slide during a stop , so now I bought some 78A shootes, and still too much grip, I guess it is somethig with the wheels when they are new, if so, is there any way to fix it, ? cos this is being a pail, I mean, literally , to my ankles , and also my game level s*ks since I cant stop without making and awkward turn . I only been playing for a couple of years, so skating level is probably an issue too, but with the old wheels I was able to do some good stops, so maybe there´s some way to make new wheels feel a bit more confortable,  I was thinking on sanding the wheel surface so they feel more like used wheels, has anyone tried ? any other ideas? I´d really appreciate your comments. thanks a lot !
