If you're going to use it with a drysuit:
VDH 35# wing - $255
Store | Vintage Double Hose
Blue Reef SS Back plate - $70
Blue Reef Stainless Steel Back Plate
If it's for warm water, then a VDH 18 or 23# wing would be a good alternative. Or the DGX single tank rig with a SS plate, for $309.
DGX Custom - DGX Singles Harness / Backplate / Wing Package
I have a HOG 23# wing and just got the VDH 35. Comparing them, I expect I would like the VDH 23 better than the HOG. I think the VDH is equal or better quality and it is a bit more streamlined. My HOG wing is about 3 years old and it has some fraying in the seams of the shell and I have seen the same thing on at least one other HOG wing. That said, I know they have changed production since I got mine, so I don't know if they still have that issue. Another thing is that the HOG wing has the corrugated hose coming out of the center of the top. The VDH has it offset to the left, so it doesn't hit/interfere with the 1st stage regulator (another reason I like the VDH better). But, again, I'm not positive if the current HOG wings are still the same in that regard.
Going forward, I will use my VDH 35 even for dives where the HOG 23 would be plenty of lift. If that says anything... I think I'm going to do a Blackbeard's cruise this summer (i.e. a week of warm water, single tank diving). If that trip happens, I think I will buy a new VDH 18 before the trip, rather than use the HOG 23. (yes, it would definitely be a luxury purchase, not a necessity)
