Soggy,
Sorry this has ruffled your feather so! You are making a broad, incorrect, assumption that everything I say is the reaction to some problem solving activity. I replied to the OP simply that I own the product. I trim my weight because I want to carry no more weight than I need to, if I had 10lbs of excess gear on for a dive, I would shed 10lbs of lead. I go from fw to sw, I adjust my weights. No Problem. As far a a relief valve being a problem, I disagree and BTW every cylinder has a pressure relief valve. Its nice to see all of you outfit yourselves the same, how would one tell any of you apart...LOL, gives new meaning to one stop shopping. My focus is having a safe, enjoyable experience diving.
