atapene will become famous soon enough
there were a large selection of those fins on trial at practice here in holland at the... barramoenda club i think? last night. some distributors here showing the wares.

the nemo fins are only going to sell for about 70 euros apparently... when they get going i will be buying them i think, or some leaders as i like the foot strap.

but like benny says, lets support these guys and get behind them and hopefully we will have some decent products pretty soon and some competition to get those prices down

Post Leader fins pros and cons

Hi all. I've using the Leader Fins UW Games 2006 for one year and I played with them the Worlds in Sheffield and the CMAS Champs in Bari. They're medium hardness, with the fin-strap. I tested the "neopren foot-protection inside" but it destroyed my feet; without it I only have some scraches. First days I didn't like fin-strap but now I become accustomed to them.

Comparing them with Quattro's, I think calves and ankles work more with LeaderFins and knees and quadriceps with Quattros. LeaderFins seem to have more acceleration, similar maximum velocity and more mobility.

Bad things: I use 5 different fins in one year. First pair have problems in the edges (they were opened in 2 weeks, and the same in two friends' pair). Manufacturers said it was a design problem, so they changed them. Then, in 4 months using them in trains and some tournaments, one had the fiberglass broken transversly... I ask manufacturers and they said me it was my problem, because this kind of fins cannot be bend; I answer I took a lot of care of them (I cannot pay 130€ for fins everyday...) but they said perhaps I usually take impulse on the bottom with the upper part... And yes, sometimes I did it, usually when the pool is deep... Then I had to buy one fin more and now I only use them in tournaments.

Summarizing: I think they're good, very good, but with a short life (too short for the economic effort they represent).

More info: Spanish finswimmers said us this days in Bari that they decided not to use Leader Monofins because of its short life...

I think Leaderfins manufacturers need the help of experienced uwh players to improve the design to find the best fins for our sport.

Hi Wim,
I think most guys have the medium blade and the extra hard would be way too hard.
Cheers,
Tan

Hey all,
I got two demo pairs a year ago. One pair is at Club Puck in San Jose. I think a few people have used them some. Both medium stiffness blade and medium and large foot pocket / strap. I could not tell the difference in size. I have tried them off and on. I used them for a solid 20 min. game / practice last night. I can walk today so I think I am getting used to them. Fast. Yes. Comfortable. No. (my feet are not shaped like Sandwiches though. My brother will probably have much more luck)
Also I am very careful of the rubber edges. In sheffield I talked to one of the Columbians who got out during a game because the fiberglass was sticking out. (very responsible I thought)

you can keep your fibreglass fins

I'm interested in seeing what the US Department of defense research has come up with

to quote

"The company which gave the world the Segway has developed a revolutionary new set of swim fins, twice as efficient as the ones worn by divers today"

http://www.theregister.co.uk/2007/08...seal_alliance/

Quote:
The Powerswim Program is developing highly efficient, human-*powered swimming devices for use by combat and reconnaissance swimmers. This program explores a new concept in swimming propulsion that uses the same oscillating foil approach to swimming that is exhibited by many fish and aquatic birds. This propulsion approach is more than 85-percent efficient in conversion of human motions to forward propulsion. Typical recreational swim fins are no more than 10-percent efficient in their conversion of human exertion to propulsive power. This dramatic improvement in swimming efficiency will enable subsurface swimmers to move up to two-and-a-half times faster than is currently possible, thus improving swimmer performance, safety, and range.

Of course, every fin ever made also operates on the oscillating foil concept, but hey it sounds cool so we'll use in our publications...

Don't think you'll be seeing them in hockey anytime soon, although maybe coaches would enjoy them.

It looks like it needs to go on one of those crazy Japanese invention shows

The problem with "efficient" fins is that they are normally made for lazy overweight scuba divers who want to expend as little energy as possible when they are in the water. However, that efficiency normally leads to a lack of power which we need for hockey. I think most UWH players legs are a bit different to those of most recreational scuba divers!
