Actually the 6 lbs was near my shoulders to counter balance me with the 80’s. With the 80’s I was massively knees down, so had to pull my upper body down. I went fro 10 lbs on my shoulders to 4 lbs & am only ever so slightly nose heavy. Being I have not had a chance to check out the trim & buoyancy with full cylinders, I want to keep it a little nose heavy to help make up the difference, if needed.
