<font color='#0000FF'>Hi Matt

It sounds like you emptied all the air from your suit before the ascent, and then cos you were vertical were then dumping air as you hung onto the SMB. You would have been negatively buoyant anyway doing that. Instead of dumping immediately rise a little first, then dump but only enough to stay neutral and then do that a little at a time. A tip for your stops is to stop at 12, 9 and 6 mtrs and then make sure you take at least 1 minutes to get from 6 to surface, pref 2 minutes. It just takes time mate, you'll get it, and its easier to use your BC for buoyancy instead of your suit, less air moving about.

The only way you'll check your weighting is at the end of your day at Stoney or whatever and drain your cylinder to 35 bar. Depending on your weight system drop to 3 mtr and hold a stop. Don't use your suit for buoyancy, use you bc. If you need air in your bc then you're too heavy. Take a little off until you have no air in your BC and only a tiny bit in your suit to simulate what it would be like at the end of a 20 mtr dive. Thats your weighting. Add 2kg or so for the sea unless you can find a still, shallow piece of sea to play in.

Hope that helps
