dbteel,Get the splitfins,any brand but the Farce Fins.I am 5'10" 190 and in very good shape(sub 5:30 miles and leg press >750 lbs per leg)I dive 150-200 dives a year from springs to rivers to offshore and currents from none to 3 kts,every kind of diving and for the past 2 years I have constantly been amazed at how well these fins outperform in every way(except price)every other fin I've seen.They cannot be "over-kicked"and there is no need to modify your kick.That is all media hype.I tried to "over -kick" these fins wearing 2x95cu.ft. lp tanks and 2x72 cu.ft. stage bottles.Wearing 180 lbs of gear in the shape I'm in they couldn't be "over-kicked" Everyone I dive with either dives commercially,as an instructor or 100+ dives a year.60% to 70% use S-P Twin-jets and are of the same oppinion regarding thier superiority.New technology is often met with much-deserved skepticism in the dive community Re:nitrox 15 yrs ago and Weight-integrated B-Cs even 10 yrs ago.Ask 20 divers from the shop you go to that have'em if they lov'em.
