I'm currently running some purple Ishod 53 classic 99's, basically because that was the biggest FF they had at my local. I skate bowls and transition 99 percent of the time, with some of the bowls around here going on 20 years old and unsealed, rough as. I've had them for about 9 months and they are now sub 50, but still feel awesome!
Like someone said earlier, it's not like they reinvented the wheel, but they are a pretty solid all rounder.
