The issue is, Force Fins are advertised and spoken about as if they are a 
break through in fin design, with the big differences suppossed to be less 
cramping, and  far more efficient thrust...so people are led to believe if 
they buy these fins, they will swim faster with less effort, without 
cramping. This is a forum where "MISINFORMATION" is addressed on a regular 
basis; Divers on this list have a responsibility to  this end.

>fins?  

I would have no problem with them if they worked as they were billed by most 
people who jump on the Internet with claims about what the best fins 
are....I have seen far too many force fin wearing divers in the water, so 
slow that everyone else in their group had to wait for them. And this is not 
absolute proof that Force fins are slow---I mean it could be that every 
single one of these divers I saw with force Fins on were just VERY slow and 
weak swimmers, and perhaps the reputation of the Force Fin pulled them in. 
This is why I made the "CHALLENGE" ---If there are any highly "fit" divers 
out there, maybe even a Navy Seal or two (who have been rumored to be using 
the Force Fins), this would be an opportunity to test Force Fins against 
what most divers consider to be "good" fins, instead of always comparing 
them to"stiff" fins. In the Challenge, the Force Fin wearing diver will just 
try to keep up with two divers who are wearing freediving fins (one will be 
wearing A.B. Billers, one Cressi Rondine Garas)... and there will be no need 
to beat the two freediving fins divers, but just to "keep up with them" for 
20 minutes on a typical spearfishing dive....If a Force Fin wearing diver 
can keep up, we will finally have an example that supports the claims that 
the fins are efficient.
 Right now, it would appear the only safe claim is the lack of cramping, 
which in most people could have been fixed by an altered kicking style and 
/or some exercise a few days per week, and could certainly be cured even 
better by just removing the fins and kicking bear foot (how much slower can 
these guys go anyway?).

Not to spoil your humor Mike, but one of the fastest and most efficient fins 
is the Esclapez brand of freediving fins, and they come in 4 or 5 colors, 
each color representing a different stiffness---most flexible for 8 hour 
long freediving days, and stiffest for highest possible speeds and/or scuba 
with more drag. Even the stiffest is not "stiff" compared to a traditional 
fin, the length changes everything you are used to in a fin.

Dan
