What fins to use for diving and snorkeling ?

I will be in Maui for 10 days at the end of May, and will be doing 2 or 3 days of diving, but most of the time will be spent snorkeling at various locations around the island. Right now I have Tusa Zoom SF-8 split fins and was wondering if anyone has used them for snorkeling. If so, did you feel they were a little to big. I have been thinking about picking up a pair of the Tusa FF-9 full foot split fins since the seem to be smaller overall and lighter, which would make them easier to lug around the island. Has anyone used the FF-9's and can give an opinion.

Thanks

Tim

I take two sets of fins. full foot smaller ones and then open heal heavier ones for diving.

If you try to use scuba fins for snorkeling, you'll just end up "beating" yourself and the surface water up with those heavy fins.

If you try to use light snorkle fins for diving, you'll wear yourself out kicking more with underpowered fins.

Full foot twin jets work for me.
