About a month ago I upgraded to a DUI drysuit. Suddenly my Scubapro JetFins (XL) wouldn't fit into my size 10 Rock Boots. It was a bummer because I loved those fins. They provided excellent power and were slightly negative which helped offset some of the trim problems I had with my old, oversized dry suit.
My LDS owner, a friend and I went diving one day to let me try some new fin options in a XXL size. He recommended either the OMS SlipStream or the Turtle. At 60 feet I was unceremoniously shoved into the silt where my ScubaPros were (literally) pried from my feet. First I was given the SlipStreams. I used them for about 15 minutes then switched again (much easier this time with a proper fitting fin) to the Turtles. I used them for another 15.
There was no contest - the OMS SlipStreams blew both my existing fins and the Turtles. First, the SlipStream is a neutrally buoyant fin unlike my JetFins. With my proper fitting drysuit I no longer need the "weight" of the ScubaPro fin to keep my body in trim. Second, like my JetFins the SlipStream actually provides power with each kick. I really did feel like a Turtle when I wore those fins, always being the slowest guy in the group despite the fact that I was finning the most (something I was not used to with my Jets).
After the dive I ordered myself a set of SlipStreams. Unfortunately they were back ordered so my LDS loaned me a set of Turtles they had so I wouldn't have to jam my JetFins on and dive in pain. I wore the Turtles for about 10 dives and hated them on every one. Especially when I'd cramp up towards the end of a dive if there was particularly strong current. Did I mention I dive in the St. Lawrence River?
Last week the SlipStreams arrived and the few dives I've put on them were wonderful. I'm back to very few fin kicks for very large thrust.
Anyway, after having a great deal of experience with the ScubaPro JetFins, the Turtles and SlipStreams I'd have to say I'm happiest with the OMS fins.
