Will I Die With A 100lb Wing?

[BadFish]

100# wing....way way way more lift then you could ever need on a Single
AL80. Ebay it.

As for the bungeed wing,
Cons:
Less streamlined.
Intanglement Hazard.
and keep in mind, should you ever puncture it you will never beable
to inflate it.
WHy you ask??? good question....

the bungees force the air out.

Get yourself a 20-30# wing without bungees....you will not regret it.

I've never tried to orally inflate an OMS banded bladder, but I've used Dive Rite Superwings in the past, which use elastic "gusset control cords" and provide about 80 lbs. of lift, and I had no problem whatsoever inflating them. But then again, they weren't nearly as tight as OMS bands.

One reason for using a bladder larger than what you personally need is redundancy for your buddy in case of a FUBAR situation.

If you start diving dual 130's with stages and a wetsuit, then you might want to look at it.

Diving 130s with a wetsuit would not be DIR as I understand it. For wetsuits, use double AL80s; for 130s use a drysuit for backup buoyancy.

A bungie wing will require you to maintain balance in your rig. e.g. if you are running stage bottles, you will need weight to compensate for that stage bottle on the other side. Ideally you'd need a way to remove the countering weight as you use the gas in the bottle. This is because a bungied wing will keep the air distributed evenly around the wing, and not allow it to equalize to your trim. e.g. if you have 3 extra lbs on one side, a non-bungied wing will end up trimming you out with 3 extra lbs of lift on that side. If you then push that extra lift over to the other side, your attitude will suffer.

the people at my dive store say i shouldnt need any more lift that 40 even with double tanks.

That might work for double AL80s with no stages - maybe one of the Tech guys can confirm this - but if you're planning on double 130s or similar and stages, a 55lb wing seems to be the preferred choice.

As for the 100lb wing, my philosophy is "if you don't need it, don't take it".

looks like every ones agrees.......don't go with the 100lbs

Vodolaz -

I don't know if you've ever tried to use your drysuit as a sole means of bouyancy, but most drysuits (especially well-fitted ones) don't have enough lift to do it, when faced with doubles and stage bottles. Try it out some time - empty your wings and see if your drysuit will keep you on the surface. From what i've seen when I and other people have done this, it may not. Even if it will, it's pretty tough to move in an overinflated drysuit (imagine being in the narrow confines of a wreck and having to inflate that much? good way to get your suit ripped.) I don't know what the official DIR line is on this, but most training agencies recommend either redundant bladders in your wings, or at the least a lift bag as a means of controlled bouyancy for ascent.

Generally you would only need your drysuit to keep you neutral enough to get out of the overhead enviroment. You couldn't really use the bag here anyway since you have the overheard. Then you deploy your bag for your stops if you need them. You don't need to worry about the suit keeping you and the tanks bouyant on the surface either because at that point all the crap has hit the fan and you are ready to ditch any equipment you don't need once you hit the surface so if your suit is already inflated you cut the harness and drop the tanks and let your surface support team save your butt.

My understanding of the DIR line is the above. This is based on duel bladders being duel failure points. If you hook them both up and one sticks it takes you twice as long to figure out which one is stuck and during that time your wing is filling up and making you positive. If you only hook one up you still have 2 inflator hoses dangling and everytime you have to adjust you have to figure out which one to use, plus it is just that much more to snag on line.

Of course others disagree and that is OK too.

Oh I should add that I am no expert and someone more knowledgable than me may well correct me.

It's not just you...it's happened more than once here very recently and it's just annoying....it is usually solved rather quickly, but just try to keep that in mind for future. Please enjoy the board.
