I appreciate the help slap pals, I ride 52-54 mm wheels so I think Im going to skip the risers.
I sized up recently. Was at 8.25 with Indy 149's and it feels great. Currently have 8.375 with Indy 149's. definitely recommend 149s with 8.25.
As for risers, for 52-54mm, i say no. I ride 52-53mm, for even big pools, street, and everything (same with grant, greyson, etc.), and even have the hollow baseplate which is 1mm lower. with standard stage 11 55mm height, you do NOT need risers, otherwise you lose stability being so higher from the ground and lose response time. If you wonder why not everyone should have high trucks with inch high risers, see mark suciu's skating. I digress..
