I'm not a fin expert, but I'll take a crack at it. My guess is that the blue one (not the Turbo Tunnel) will slow down the cutbacks for you. Bigger base, not as loose, longer radius turns, more drive. Probably also that funky fin being that it has the bigger base and a lot of rake. (If you try it, post up your report! Reminds me of the hotels in Wildwood, NJ. If nothing else, it'll be a conversation starter.) Everything else looks like a narrower base, so looser turns.
