I know you're talking longer than 31, but a Cig 31 Bullet is actually longer than your 31 Formula, since your has the molded in swim platform. Will almost guarantee a better ride than yours and most boats that are even longer. A friend with a 35 Formula swears mine rides better than his. Anyway, nice cabin working head, Vberth, 502s, new interior, paint,...on and on. Just bougth a TG so my baby has to go. Pics on website.
