    Weight belt? :) Slung on the left, don't even know it's there. I never dive without it, it's part of my configuration. Purely from a weight standpoint, a 19 cu ft tank is about .5 negative full, plus reg and hardware, about -2.5lbs total.

    My camera does affect my weight and I can pull off about four pounds for it, assuming I have any, 19 and 30 cf auxilary bottles just do not seem to cause an issue other than hitting my camera somtimes.

    I've been diving with a Pony about 20 years, so I don't recall what I did to adjust for it because it was so long ago.

    You can probably check the weight of your pony and the buoyancy on the manufacturers website and do a simple calculation to see how it will affect your weighting. For example, if it weights 9 pounds and adds 2 pounds of buoyancy, my guess is that it is adding 7 pounds of weight to your kit, unless there's something I'm missing (and I'm sure someone will jump in and verify that).

    Thanks, for all your inputs, I wrote late night and went diving early today, did not had the chance to look at this post since, I did, pull 3 pounds of the belt, but it was not needed like all of you mention, I had my pony bottle on my right side on the back like a double, only thing I noticed is that I needed those 3 pounds back.

    Thanks anyway, this post will be useful for others with the same question in the future.

    after tomorrow I will go for solo exploration and see if I BBQ some Lionfish.

    I shifted 2 2-lb weights to each tank strap on the left side. I'm able to roll fairly easily and swim sideways. I'd suggest experimenting and see what works best for you.

    I shift a pound or two to the other side, dropping that weight could cause an issue if you had to hold a deco stop with an empty tank while emptying the pony. I carry two to four pounds over ideal for an empty tank scenario, so when I add a pony I don't have to add weight for a depleted pony since my lung volume should make up the difference. If I was using ideal weighting, I would add at least two pounds opposite the pony.

    I don't usually carry the pony, I do when deep solo and the issue of deco could rear it's ugly head, so I plan accordingly.

    I do not drop any weight as I am willing to hand off my slung pony should the need arise. I usually have at least a couple pounds on a weight belt (usually just a single 2 pound weight) and I will push that weight a bit to my right if I feel like the pony is rolling me.

    When I had my 19cu ft mounted on a bracket to my primary tank, I would take 1 pound off (total weight) and then switch weights to be 1 pound "heavier" on the opposite side. For example, pony mounted on my right, so 17 pounds total, with 9 pounds on my left and 8 pounds on my right (diving in a drysuit).

    However, since I've switched to slinging my pony on my right side, I have found that I don't have to move the weight around and I can wear the weight equal on both sides, although I now pull two pounds off if diving with my pony. My trim is fine that way and I don't notice the trim swing with the pony slung for some reason.

    I strap my 19cf pony to the right side of my main tank using a Quick Draw mount or I sling it under my arm on my left side, deco style. With my big steel 120cf tank or my aluminum 100cf tank (and the pony), I don't use any weights and once underwater, don't feel like my rig pulls either way.
