Well, as Tobin George often explains, your wing needs to do two things: Float your rig at the surface, and compensate for the buoyancy your exposure protection can lose.
With a single tank, about the most gas you will have is with a 130, which is about 9 pounds of gas you intend to use. Assuming you are using a SS plate, that's another 5; 2 or 3 for hardware on the harness and 2 pounds or so for regulators, and you are looking at 20 lbs or so for the rig itself.
Wetsuit manufacturers don't post buoyancy data, but a quick experiment once showed that a 7 mm suit could lose up to 23 lbs of buoyancy at 100 fsw. I know my dry suit and undies are about 30 lbs positive, so I could conceivably lose that much lift in a flood. (In practice, you never really lose ALL your buoyancy when your undergarment is wet.)
So a 32 lb wing is probably adequate for any single tank diving. A 45 is much too big, and will get into "taco" problems, where the side pontoons flap up above the tank, trapping gas that is hard to get to the inflator or the butt dump to vent.

It would be really cool to take a drysuit wearing mannequin, zipper slightly open, both neoprene and fabric, flooded to 100ft and attach a scale under the lift bag, I think.
I use a 44lb wing for double lp 100s no problem if that means anything.

Thanks for your thoughts...although the 13# difference in lift exsist between the OMS and the Venture Wing both seem to be close in physical size. Do you think the taco effect would be similar in both wings ?
Well, somehow, the two wings HAVE to be different in size, if they have different lift, because the bladders have to be different.
I don't know about the specific wings you are looking at, but I use a DSS 30 lb wing for cold water diving with a steel tank, and it does not taco and vents easily.

I have an older Venture wing and it's OK. The newer ones, in my opinion, are a little bulky for a single tank. The DSS wing is very compact and streamlined, more so than the Venture Wing, once again, in my opinion.

Out of curiosity, why these two? (Personally, I would prefer a DSS, Oxycheq, Hog or Halcyon wing. But YMMV.)

I too am looking at the Venture wing 45lb vs Hog 32lb. Because of the shape of the Venture wings trapezoid shape, it is supposed to help level off taller/heavier divers that need more lift at their center. I am 6'1", 250lbs and dive with single LP95's alternating between 3mm and 7mm suits. If there is someone that has actually used the Venture wing, I would like to hear your opinion.
