Weight question

[scubanut]

Thanks for the replies, Chris I'm talking about single tanks, soory should have clarified, and diving a wet suit (7mm) full.  The only thing that will change is my tank.  I looked up bouyancy figures online, and as I stated, every chart you look at is alittle different.  I came up with Luxfer AL-100 Full -3.9, empty +3.5, PST E8-119 Full -10.5, empty -2 lbs.  The difference in empty bouyancy is "roughly" 5.5 lbs.  I use 14 lbs with my 119, so I should be at 19.5-20 with my AL100.

I'll give it a shot tomarrow, I'll have a bunch of extra weight along in case I can't get dialed in with my figurin'!  Let you all know how it turns out..

Thanks again
Chris
