I'm at that stage

[Garf]

Where I need a stage!

Well, perhaps not yet, but I want one for when I do my deco procedures course next month.

Anyways the question. I'm diving a recwing with twin 12s. If I add a 7 ltr (ali or steel) am I gonna need a bigger wing

[Sandman]

In a word, NO. I used to dive a Rec Wing with 12's and 2 steel 7's without any problems. Size isn't everything.

Cheers

Get yourself a 7ltr ali and you won't even know it's there. So if your wing is doing a good job now you will not need to change it, the only thing against getting an ali cylinder is the price.

Whoever told you that was merely trying to make you feel better

Thanks for the advice though chaps, that's good news

Faber light weights are good as they go neutral when empty, in fact they go neutral at about 100bar and slightly float when down to 50bar in my experience. The Alis are very floaty when empty so you might need additional lead to cope with a potentially empty positive stage especially if you upgrade to two. CE marked Alis are also heavier on land and are more expensive to keep in test so the initial purchase price is not the 'only' consideration.

Mark,

you forget that the weight of the first stage offsets this. You don't need extra weight with Alu.....

As for the "extra cost", who's telling you this? you're being fed a line matey

Personally I prefer steel stages as I have shortish arms, so the narrower profile means I can reach round a steel stage more comfortably.

Obviously the best thing would be to try each in advance - your instructor might be able to help there?

Where are you based? PM if you fancy borrowing a 7 steel for a dip in Wraybury.

The same is true of steel so why bother?

The extra cost was told by Kent Diving, Dive Macheen, Blue Ocian diving.....

Mark - is the 7L in your picture completely floating, or just tail-up?
(ie if you let go of the boltsnap would it go up or down)?

Just curious to know how they compare to the old & new Al cylinders.

old debate. it seemed pointless after typing it
