So I'd been skating on G-rods for a year and had to replace them every 3 months (just so you know how much I skate-3 practices a week, 2 hours long and games every other weekend) and was super frustrated that I was having to drop a bill every few months. Then I tried the skinny heartless--woweee(yah, I'm from Arkansas)-- it takes a bit to get used to the difference of not having as much surface area to skate on but my spinning off blockers improved. However the stalkers balded out in one month! So then my coach suggested these and I'm impressed! I've skated them for a few months and they still arn't bald! Plus they are super grippy so I can jump the appex, get good grip while I'm stepping back and forth through the pack, and get a good spin off! BTW I'm primarily a jammer :) I definitely recommend to jammers or blockers needing a good pusher wheel!
