Greetings dantfarley I would be careful with the size of the wing and actually try several before you purchase one.
I tried a DR Classic, DR Rec wing on my HP 100's and stuck with the Rec wing as it was a lot cleaner and worded well with a 02 bottle / Al 80 stage.
I would consult my instructor and seek out his advice and or try several as suggested.
BEWARE THE DOUBLE BLADDER! Unless you are diving wet all the time do not waste your cash!
They are more bulky, create another hose / failure point, make more drag,etc.
Almost everyone I have witnessed buying them has regretted it and ended up buying another single bladder wing.
If you are diving dry and carrying a lift bag you are well with in your requirements.
If you find you are not move into the bigger more lift wing.
If you diving the springs a dry suit is not a requirement but makes the 70º water so much nicer for longer dives.
Be very deliberate when asking your instructor what you should be looking at for the dive goals you wish to accomplish.
OMS makes great stuff and a lot others do as well just do your research as there are a ton of BM stuff used out there that is in great condition.
Lots of divers getting into SM and selling their BM rigs.
Guys like myself just keep buying more, Why?
I can not help myself!
It is getting stupid crazy and my wife is putting her foot down.
Best advice get your gear TRAIN HARD, move with purpose and progression, master skill sets, gain experience, go not keep track of how much $$$$$ you spend, JUST DO IT.....DIVE!
See where it takes you.
You might be writing a post on SB one day and think back to when you first put a set of tanks on.
Best day ever but most expensive thing I ever did!
CamG Keep Diving....Keep Training....Keep Learning!
