I went home and compared the "turbo" fins to the regular ones I have. The supposed turbo are only slightly bigger (same width and not even 2" longer). I can't see how that's going to make much difference. I didn't test it in the water because I didn't want to get them wet and loose the ability to return them. Returned they are!
I need to compare the size of the standard vs turbo fins on my Island kayak - hopefully this weekend if the weather cooperates - as the difference was much more noticeable both visually and in the amount of power they provide.
If Hobie has any actual information on the power difference between the iTrek standard and turbo fins, I'd be quite interested. Spending $200+ per set of fins for not even 2" of difference just doesn't seem worth it.
