Lol even the Cast 148 t1 feels too low for me...
I will say, T1s are low key THE BEST for heelflips
I have to either put very small (sub 50 mm wheels on) or cut wheel wells or add risers to normal Thunders, as well as have them on a shorter wheelbase board, or redrill the deck to bring them in, which I have done and it works fine on the 8.38 x 14.5 wb I usually skate, both drilled right beside / almost on top of the existing holes and then filled the original holes with dowel and they work well, wb measures about 14.1 to 14.2 or so now.
At least I know what I like and will change anything to get it to that point, but it is a lot of work, just to get it to that point, whereas other product, I don't seem like I need to do half the things, or some I can even put on and be happy as is, eg T-II with 52 to 53 mm wheels seems to work great.
Others I skate with who run tighter trucks will ride the 148s with 54 mm Conical Full wheels and not have issues, or similar, but I need a bit more turn and height to be happy there.
* I had something like this as a basic info sheet for people setting up boards a while back, but it is still subject to truck tightness.
Truck at 52 mm = wheels under 50 mm or 52 mm max
Truck at 53 mm = wheels under 52 mm or 54 mm max
Truck at 54 mm = wheels under 54 mm or 56 mm max
Truck at 55 mm = wheels under 56 mm or 58 mm max
People said that did help them with adding risers or whatever needed - at least with the rubber 1 mm and 2 mm risers, or thicker hard risers, it was easy enough to add those in if they were on lower trucks like Thunders, before people were already out the door and then had issues.
