I've been going back and forth between a Saito 180 and YS 140 sport.

The othe option is a Saito 220. I wanted to get opinions on how it'll do in the DP Ultimate. Too heavy? The Saito 220 weighs 6 ozs more than the 180 and YS 140. Do you think I will have to reinforce the firewall? I am also considering the YS 160, but it is backordered everywhere.

THANKS!
