OP, both wings will work equally well but I like the Dive Rite. I've used the venture wing with a single tank and loved it. This one with 5 lbs less buoyancy would be even better. However, I'm choosing the Dive Rite based on something else; your not going to beat Dive Rites service. Have a look at their manufactures forum and see for yourself; I see that you can't get Oxycheq to answer your quarry as to where to buy the wing in question. I always look to see who answers their customers and takes care of them before I buy any gear.
