Hey G,

A quite standard config for twins would be the twin 12's - Faber. Most of the 'usual suspects' on here dive them with their respective choice of wing and harness. If ya need more, just ask mate. HTH.

<font color='#000080'>Hi Kinetic,

I dived for a few years with 10's and found that the 2nd dive wasn't as long as I would like so I switched to 12's and wish I had done it ages ago.

Also the weight difference is hardly noticable IMO.

HTH.

Safe diving,
Steve.

<font color='#000080'>OK, I use 300var 7's, but I've found 232 10s fine for mid-rnage stuff. If you want to go a bit further, you're going to find 12s are almost standard issue for deep stuff.

You may have problems with 300 bar trimix, and here and there with nitrox, so the 232 option seems sensible. That said, a set of 300 10s are nice and heavy, so less weight on the belt. Then again, by the time your diving is into that sort of territory, your weightbelt's as good as gone anyway.

<font color='#0000FF'>I've got twin 10s, they were a reasonable buy S/H which &nbsp;was the &quot;carrot&quot; , they're small enough that I use them for all situations, even training in 6m, I'm not sure If I would do this with twin 12s, bearing in mind this would tend to be shore diving. I guess this is dependent on body size and fitness.
But if you plan to do lots of deep stuff I'd say you'd be better off with 12's

<font color='#000F22'>I consider 30 mins the minimum dive time on a wreck. I am not talking about total time on the dive, I meen time on the wreck.

Did a 70min dive with Andrew on Friday and we got 30 mins exactly on the wreck. We wanted more but dispite doing a gas switch to deco at 21m we still only came up with 90 bar apeice. Not a big reserve at 45-50m. We wanted a 40 min bottom time but found that twin 12s would limit us to 35mins with a reasnoble redunduncy in the gas.

Our SAC on the 50m dive was apx 15 lpm

So twin 12's limit our dive on a 10@50m 20@45m dive

Twin 10s are not an option in this range

Twin 10s are not a two dive option in the 30m range

Twin 10s are a good option for two sub 20m dive or one 40m dive

To me thats too limiting in the dive profile

Cheers All....that's been a big help.

I'm tending towards 12s for the reasons Mark gave....

Really appreciate it.
