FWIW, I did the drop 4 lbs and then another 2 lbs.
With only dropping 4lbs...
I felt a little heavy on safety stops,
but I was still able to empty my wing all the way with an empty tank.
If I had more than say 700 psi then I would need to have the wing slightly inflated.
Got rid of the other 2 lbs. and everything checks out.
It took a bit for me to start my descents in an AL80 and jacket BC,
but I was properly weighted and I wasn't hitting the sea bed
stirring up silt like some.
