Thats proabably a really good idea if a drysuit makes sense in your locale. A drysuit can help keep your baseline bouyancy consistent throughout the course of the dive, so you're using your wing for bouyancy control, offsetting the current weight of gas in the cylinders, and not having to compensate for the variable lift of a thick neoprene wetsuit as it compresses at different depths.
If you're able to configure a truly balanced rig, you'd be starting the dive around 13-16lb negative (160ft^3 of air = 12.9 lbs, 200ft^3 of air = 16.1 lbs), and you'd be nearly neutral with nearly empty tanks and an empty wing. 16lbs of lift in any 40lb wing is less than half full, and you'll be dumping wing gas throughout the course of the dive.
As long as you're not going fringe with some of the wierd wing shapes/features or using a big floppy 60lb wing for just a set of 7.25" doubles, the wing brand and model doesn't really matter much as long as its made of quality materials and reliable. Essentially for what you're describing literally any decent 40lb donut shaped doubles wing from any recognizable brand should get the job done. You could pick a wing because you like the color, the price, the material, or just because its in stock at the local dive shop.
Fins matter, masks matter, computers matter, wet-vs-dry matters, but the logo on your backplate and/or wing doesn't really affect your diving in the slightest.
