I have over 100 dives on mine since September living here in Florida. Ajduplessis is correct, they tend to silt up the bottom more than the old style Jet Fin. However, I love mine and have worked on my kick or modified kick to keep the fins off the bottom. If you have good buoyancy and remain vertical in the water and use the modified kick, stay off the bottom, you shouldn't have a problem. I don't think I would use them in a CAVE situation at all, but for Ocean and most sink and clean Caverns, they are great. The really move you along using the Dolphin kick.
One thing I do notice, is it is just cosmetic, but after so many uses, they are really scratched up and look ugly. I was going to order a white set but because of the scratches on the black pair, i decided against them.
I also for some reason, and I have found nobody else with this issue, I now use a rear entry from a boat as about 25% of the time using the front scissor kick entry, the trailing fin will pull off my foot and the entire fin would travel up my calf, thus a terminated dive unless you have a good buddy willing to assist in removal of the fin and placing it back on. Since I switched to the rear entry, I have never had a problem. I have Deep Sea booties and I notice they do not have a large fin strap keeper so this could add to the problem as well as maybe a lazy entry. I am a size 10 and wear large Nova's, this is the crossover size so maybe a medium would also fix that problem. But I like the fit of the large, might try a set of Mediums or buy a different bootie as mine have just about had it after 150+ dives. Deep Sea's are not the most expensive in the world. I had a set of Pinnacle 5mils and required XL fins so I sold the Pinnacles, just too hot for our water.
One more thing, these fins are positive buoyant. Until I got used to them, I used 1/2lb weights on each ankle but then found myself silting up the bottom too much. I think I had more of a general buoyancy problem that I have since fixed. It is nice to know that they float and do not sink.
I have no other fin at this time for my type of diving that I would consider. Hope this helps.
Also, please support your Local Dive Shop. You can't buy air from Ebay or LP or any other online dealer. I said in an earlier post. In Florida, the economy is hitting the shops without boats hard. Since my last post, we have had two more dive shops close their doors. With this oil spill in the Gulf, I have a great fear what could happen to all the reefs in Florida as the oil is starting to get in the loop, or the Gulf Stream. Just my two cents. All you divers buying your stuff online, when you come down to Florida and we have fewer dive shops, then you are going to be paying a prime price for air/EAN and TRIMIX. Think about it.
