I had an opportunity at Dutch Spring last week to test out my Hollis F2s and the new Deep Six Eddys.The sizes are, respectively, Small and Large. The large Eddy is just a bit too big for my foot/bootie, but I've ordered some new Poseidon One Shoes that I hope will fit a bit better.
Lengths are similar, the Eddys being about 2 inches longer, but the same width within a quarter inch. Their weights are 3.6 pounds (F2) and 4.6 pounds (D6).for the pair of fins. [For comparison, my old Dive Rite XT fins, size Large, (plastic buckles) are 4.9 pounds and my new XTs (metal buckle) are 5.9 pounds. Length is about 3 inches longer than the D6 Eddys, width about the same.]
In fresh water, both the D6 Eddy and the Hollis F2 sank very slowly; I expect both are slightly positive in salt water.
I swam a measured course (the length of the platforms near the instructor entrance) with the F2s and the Eddys. The number of continuous fin kicks (frog kick) was essentially the same for the two fins; however, using a kick-and-glide motion, I reduced the number of fin kicks by 10% with the F2s and 25% with the Eddys. thisb is a significant difference and tells me the kick is more powerful with the Eddys and gives me more glide. I wish I'd had my XTs with me to repeat the test!
