Strike,

>As its my intention to only ever again dive a single cylinder, (mines a
steel), I'm opting for the same lift as my current wings give me - 45lb
lift.  However, any advice or opinions on this would be greatly appreciated
before I actually part with the hard earned dosh!<

45lbs with a single tank (even steel) sounds a bit much. 27 lbs is enough
to float your gear in those cases where you take it off while still in the
water, even when the tank is still full.
