Oceanic Viper fins?

[cbope]

I'm looking for a new set of open-heel fins. I was planning to get the Mares Avanti's after extensive research, until the price shot up nearly 50%. I've noticed these Oceanic Vipers on ST. The design seems to be fairly similar to some of the Mares fins. The price is very good too, compared to the current price of the Avanti's.

Are these Vipers any good? I'm looking for a good multi-purpose fin, not too soft and not too stiff. I've got pretty good leg muscles but long legs so a too stiff fin can be a problem. I'm not looking for the most powerful or easiest fin, but something that has good efficiency and is not too heavy for travel.

Nobody has the Viper?

Ok then... rather than take a chance on an unknown and since the euro/dollar exchange rate is more favorable now the Mares are not too bad of a choice (still much more expensive than the Viper though).

So, Avanti Superchannel or Avanti Quattro? They both get generally excellent reviews, but I'm leaning towards the Superchannel. Slightly cheaper (ST) too.
