It was interesting to read the different thoughts on weight. I dive in a tri dry suit with a LOVELY thick fleece bear, I use 28 lbs, distributed between my hips and my ankles. I am 5ft 6 and weigh 9.5st (sorry dunno the conversion) I dive with a 10ltr aluminium tank.
My BCD is heavy as it is a Buddy jacket with auto air.
I get moaned at by people for wearing too much weight, and I am trying to reduce it. On a twenty plus metre dive, I really notice the weight at the bottom.
I have been able to get down to 24lbs but that depends A LOT on the day and how i feel. If i use a 12ltr tank, I get down to 22lbs.
What I have worked out is that stressing about people going on about the weight I use, only tenses me up (making me less likely to be able to lse it) so now I go with the flow. I put spare on the boat so it is there if I need it, I look at the surface conditions, what the dive conditions are, and how I feel and don the weight I feel is appropriate.
My only advice to you is not to stress. Stress and you will stay heavy. Chill and it will come.
