Steve Let me join the throng and add my HO after all the nonsense so far. Firstly, the argon bottle vs. V-weight issue. I moulded my V-Weights slightly narrower than the gap between my doubles. This allows argon bottle webbing to be in place and a V-weight to be used. It also allows me to fit inner tubing bands around my doubles and I use this to carry my pre-packed lift bags on the side of my cylinder, tucked close into my body and out of drag and snag with my wing wrapped around them and the cylinder. However, you solved this by cutting out a notch in your V-weight, so this would not solve the problem. However, do not discard your V-weight yet... Secondly, it seems only sense to take a primary light if you think you may need it, and not, if your are certain that you do not need it. The beauty of DIR/Hogarthian is that one can dive it in 99% if circumstances and in all circumstances that I dive. I did a few recreational dives recently and still dived with Hogarthian rig set for recreational use. This meant no canister light for the 20+ m vis dives to 20 m. This is only common sense and DIR principles that you take only what you need, so no issue with what you are doing here. Thirdly, if you are in circumstances where you light is not required you say you need your 6 lb. of weight. There are a few options for you to consider, which you may have already. Since you are referring to trim and putting the weight on your belt, and tried cutting a notch in your V-weight, I assume that the trim your are experiencing is a head down attitude. This happened to me when I first set up my rig. Without messing around with pockets and weights, first ensure that your cylinder bands are as high on the cylinders as possible so as to push your centre of gravity towards your feet. If that does not solve it, lengthen your harness straps, and tighten your crotch strap. I found this fixed my problem. The harness although slightly "loose" did not slop around and also made getting in and out of it easier. Also, if you are carrying stages, check that the position of the upper D-ring is not too high. This will have minimal effect unless you are carrying steel stages which I assume you are not as you are reported as being very DIR. In one configuration, I found that I need 5 Kg of weight. I can only get 4 Kg as a V-weight, so I made a bolt-together weight. That is, two V-weights that bolt together so as to keep the centre of gravity low. The bolt is permanently moulded into the rear-most weight and completely hidden at the rear so there is no snag potential on this. The inner V-weight has a hole to take the rear bolt and a recess for the nut so that it all fits nicely behind the backplate. Also, the rear weight is a precise fit at the rear since again to avoid snags. This could be an alternative V-weight solution for you to consider. Maybe some combination of a few of these ideas may solve your trim issue. They did for me as I felt that to carry a weight pouch was intrinsically wrong as it must have been with you, hence your email.

A solution was to notch out where the argon bottle strap goes. This still did not provide good trim for me. so I moved it. I still need the weight (all of 6 lbs), but not as a V-weight. This is when I am diving without my canister light. When I use my canister light, then no weight is needed. My canister light is not 6 lbs negative, only three. I use 6 lbs as smaller weights move or fall out.

There, I said it without an insult.
