Question on Gator Caddy & Ricky G

I have a Caddy 142, and I like it but I always feel like the board wants to go switch on me. Maybe I am not on the edge enough. I was wondering if this might be due to the lack of a center fin, it just has 4 molded fins. How would a Ricky G feel, since I beleive it has a removable center fin system. Is it a much faster board than the Caddy, how does it compare on pop and landings.

Thanks for your help!
