40Lb or 60Lb Lift?

[WHITES Justin]

Hello all,

Just a quick question; I have recently purchased a twin set of Steel 100 doubles and am not sure whether I should get a 40 or 60 lift wing?

I was leaning towards the 40 as I don't want alot of extra wing flaping around, but a buddy of mine who dives the same double set as I am getting mentioned that he felt slightly negative on the surface so he upgraded to the 60 lift wing.

I appreciate the feedback!

Cheers,

JB

In doubles required lift is a function of the buoyancy of your exposure suit and the weight of your gas.

2 x 100's will have about 16 lbs of gas. If your exposure suit is more than about 22 lbs positive with minimum gas in it you will need a wing larger than 40 lbs.

I agree with Cool Hardware. You don't want to come up short in bouancy at the surface, especially in a critical life saving situation at the surface. This is even a greater concern of your partner is wearing his own set of double 100s. As to the flap, I have overcome that problem years ago when the At Pac ans ScubaPro BCP first came out (mid 1970s) with elastic bands at the sides of the BP that holds the wings in place.

I dive double 100s in Puget Sound wearing a Bare compressed neo dry suit with 4th Element undergarment and use a 40 lb wing. It does keep me afloat -- but sometimes just barely! I've purchased a new, bigger wing.

YMMV

A few pounds more lift is significantly better than a wing that falls a few pounds short.

Gooday. How does the fabric cope with elastic band compression on the SP wing and how did you install it? Thanks.

Right now, I’m using a 40lbs with the HP100s.
My suit is ~+23-24. (measured in a pool at 19-20, without fins). So with BP, regs/manifold,band, and light (-2), I’m adding an extra 3 pounds of lead and it seems find to maintain the stop (while there were more than 500psi left).
That would lead to a total ballast of –[(BP=6)+(Regs&stuff=6)+(Light=2)+3lead +(FullGas=20) ] = -37lbs. The wing is at the limit, but float the rig easily in fresh water.
I would not consider a 60, but indeed, look at different wings between 40 and 50 and other options: quality, shape, OPV placement, etc …
