30 or 40 lb wing?

[Storker]

my steel 12 fabers are 13.4kgs. Some 12l euro cylinders around 14.5kgs.

That might depend on whether they are 200, 232 or 300 bar, no?

My 15L 200 bar tank weighs more or less the same as my 10L 300 bar tanks. I had a 15L 300 bar tank for a while, that beast was 24.5kg. Plus the valve...

If still in doubt (and no one else has linked to it that I've seen) here's a wing lift calculator, conveniently stickied in the BCD subforum: http://www.scubaboard.com/forums/bu...ems/158370-ultimate-wing-lift-calculator.html

they are 232 bar, which are by far the most common tanks in the uk

OK, gotcha. The 300 bar rated 12L is a rather popular single up here among those who (think they) need a little more gas than the ~3000 surface liters a 10x300, 12x232 or a 15x200 can hold, so I assumed there was some potential for misunderstanding.

I went with a Hollis S38 Lx - has internal retraction bands that can't get snagged so it stays nice and tight -- no taco effect at all. Very happy with it.

FWIW: I dive dry with Faber Fx100 steel tank, 5lb ss plate, and either 6lbs or 8lbs of weight depending on what undergarments I have on.

I wouldn't mind one bit ... having gone through that particular line of thinking myself with my first wing purchase. The downsides, simply put, is that the wing is designed to accommodate both singles and doubles ... and therefore is not optimal for either.

I started out with a Dive Rite Rec wing. I borrowed a friend's doubles wing and tried it with my dual 119's, and realized how much performance I'd been giving up on that side as well.

I've been using an OMS doubles wing and a Halcyon doubles wing. I just got a DR Rec wing and used it for 6 dives in the last week with my double HP120s. I left the bungee on at first, but unthreaded it from a couple of holes so it didn't compress the air cell at all when fully inflated. Then I went ahead and just removed the bungee. I felt like it worked a LOT better for me than the Halcyon (Explorer 55) and was pretty much the same as my OMS (60) wing for buoyancy and trim and is much more compact and streamlined. I.e. my experience is that a hybrid wing CAN be fine for doubles.

But, you used the same wing. So, what wing did you use that gave better performance? And how exactly did you feel like its performance was superior?

... it's billed as suitable for singles or doubles ... try using it on a single rig, comparing it to a DSS Torus 35 or Halcyon Eclipse 40 and you will be able to answer your own question ...

As for using it as a doubles wing, the Rec wing has a smaller inner panel (by necessity as a "hybrid") than a standard doubles wing. As such it tends to trap some of the bladder under the tanks ... particularly when using 8-inch diameter tanks such as the 119's I mentioned in my post. I compared it to the Halcyon Evolve 60 and the DSS Torus 49 ... both of which gave me better overall performance than the Rec wing did in terms of overall stability and ease of dumping gas. I did not, as you did, remove the bungee since the wing is designed to be used with the bungee in place.

You specifically mentioned improved performance with dual 119s. I don't plan to use it for singles, ever. So, I was just curious what you found to better about another doubles wing versus the DR Rec - for use with doubles. I see what you mean now. And, yes, I don't think I would try using this wing with 8" tanks. But, for my 7.25" 100s or 120s, it seems almost perfect (for use in warm water). Not too small and not too big. Just right - for that fairly specific scenario. In cold water, I will use my heavier back plate, dry suit, and a bigger wing.

Hello,

after 6 years of bcd diving,i am considering buying a bp/w.
but i dont know if i could better buy a 30 or 40 lbs wing?
i dive a single 12 steel tank in a drysuit in cold waters.

pros and cons and why?

thanks!

Based on what you wrote, assuming you still want to dive the same configuration for the past 6 years, then do the following, lookup what is your BCD lift capacity, and match it to the wing capacity that is similar, if a 28lb lift BCD was doing the work, a 30lb wing will work as well

Another question if you don't mind: Why are bungeed wings frowned upon? Is it just the entanglement hazard or is there more?

The stock answer is that in the event of a puncture or leak the bungees would squeeze all of the air out of the wing. Unless the leak is at the top of the non-bungeed wing it will still hold air.
