surface buoyancy is an issue at the end of a dive it can normally be solved by letting the tanks hang – i.e. removing the bungee attachment.
This is best done while still underwater, I normally remove the long hose, coil it and clip it to a small bungee around the tank neck before surfacing, it’s also easy to remove the necklace from the primary (left) tank and untie the bungee attachment while still 1-2m underwater, hold the tank in place until your at the surface, inflate then pop the LPI connection and let the tank hang – this keeps both tanks in the water and therefore neutral or positively buoyant so all the BC lift is used for you, not holding tanks above the waterline.
+1 I do something very similar routinely. On safety stop/end of last deco stop, I re-stow/tidy my right-hand cylinder and remove it entirely. I then repeat with the left hand cylinder, leaving the reg and LPI attached for the final ascent phase. Upon surfacing/inflating, the cylinders are free and ready to be immediately handed up to the boat...and I have zero problems with buoyancy.
I will sometimes also arrange a drop-line beneath the boat to attach the right-hand cylinder (and any deco tanks) to, before surfacing.
If this still isn’t enough you can always use a DSMB on the dive and use it for additional support at the surface,
DSMB works great under the armpits for any extended surface float.
