Thank you for entering the discussion, I cannot deny the fact that you have many followers, I would love to try them out one day but I feel as though they just wouldn't sell me. I would have no problem paying $150.00 for the original force fin, not much more than my Mares Quattros, but the force fin still hasn't in my eyes claimed any national acceptance, In fact I haven't even seen a pair to be quite honest with you at any dive shop. I've maybe seen 1-2 pairs on dive boats, the last pair I seen was hanging up at the wheel house, the owner of the force fins strapped on a pair of twin jets. Word of mouth travels fast especially in the scuba world...why do you suppose that the many that love them haven't hooked others divers? unwillingness to try other things maybe. they certainly are radical. I'm more than a skeptic however not unwilling to try new things, maybe one day...not March 15th, if given the opportunity that I would certainly try them. I have no doubt that love, craftmanship, dedication, and heart goes into every tandelta you produce, but I fail to see any benefts from paying $800.00 for a pair, especially since there are so many excellant choices out there using traditional blade technology, nevertheless fin doc, I wish you many sales and always safe diving
