DiveGearExpress (
Dive Rite Express is now Dive Gear Express) handles the entire DiveRite line of products. They are an excellent supplier.
Just to compare prices, why don't you look at
www.deepseasupply.com ? There is configuration page
https://www.deepseasupply.com/index.php?page=rigs Of the several times I have priced high end components, by the time I got the total, Deep Sea Supply was not just competitive, they were cheaper. The gear and customer support are excellent. I bought a couple of these and some other equivalent BP/Ws and I prefer the DSS for price and quality. I am a huge fan!
But the exact configuration will be very dependent on the kind of diving you intend to do. If you dive in cold water with a lot of weight, a stainless steel backplate is probably the way to go. If you dive in warm water then maybe an aluminum plate. If you want to travel and keep it light, maybe the OxyCheq Ultra Lite Travel Plate would be interesting. Be aware, it is fabric and doesn't provide the same support as a metal plate. DSS has a Kydex plate - very light.
If you start looking at OxyCheq backplates, you might consider
Add Helium They have great prices on this stuff. OxyCheq makes a dog-bone shaped stainless steel travel plate. It's pretty light (2# ?) and it provides a lot of support. Their Mach V wing is highly regarded.
Some wings have ribs or blocks to prevent the tank from rolling. These wings work well without an STA (Single Tank Adapter). Other wings don't have this feature. The DSS wing has a rubber V block, the OxyCheq and HOG wings have ribs. The Dive Rite Venture Wing doesn't provide any support and is probably best used with an STA.
If you want to move even more weight to your backplate, DSS has some weight plates that mount to the backplate and put another 8# on your back as opposed to your hips.
Wing lift is a separate issue. I'm not even going to get into it because it is highly variable. I use a 30# lift for cold water diving with a wetsuit. For doubles, you need a lot more lift and for warm water diving perhaps somewhat less. There is a sticky "Ultimate wing lift calculator" at the top of this forum. It is interesting to play with. It might not be the final answer but it does provide insight into how much lift you might need under different conditions.
The best way to settle the wing lift issue is to call Tobin at DSS. He has this down to an art form.
