Venture Wing or Trek Wing?

I'm going to buy a TransPac and will only be diving singles. Should I get a Venture Wing or a Trek Wing? I like the gusset cord on the Trek Wing but am not sure if the 40lb lift capacity will be too much. Does the Venture Wing flop around alot since it doesn't have a gusset cord?

Also, why is the Venture wing round so that the air can go all around but the Trek wing is horseshoe shaped? Does it make a big difference in buoyancy characteristics or trim?

Any info is greatly appreciated since I'm stuck between the two.

I would say go with the Venture. It will not flop up and "taco" your tank because it is not big enough to do so. The shape was designed to give people more lift on the bottom of the aircell so as to help you stay horizontal in the water. Again, go Venture.

Cheers
