I'm a gearhead/nerd, my excitement for these (or any new truck) was same as it was for the indy mids (well an indy mid ti), Lurpiv and the upcoming Tensor redesign.
8.25/8.5 sizing (no 8.3s ML/ACE C)
Mid - 51-53mm (always been my preference)
Lightweight
Turns like an ACE/Indy/Theeve/ML
Good grind clearance
Doesn't stretch the wheelbase out too far
Doesn't have fucked QC (jury is out on the royals)
IKP (optional, I tinker with my shit so having this option is a bonus)
I don't care who makes it/what brand, and would been camp lurpiv if they weren't 55mm, I don't skate transition or big wheels enough to need a truck that tall.
Low means different things to different people; I consider low to be anything ~51mm, less than half the Thunder models can be 52mm. if you opt for team plates.
Standard 55
Mid 52-53
low 49-51
51 and 53.5 are sort nebulos neither a low or a mid. And no one makes a 54? Indy forged being the closest at 53.5.
If tensor ATGs were mids, I'd not skate anything else. They grind better than anything out there and I haven't bent any axles.
