<div style="right: auto; color: rgb(0, 0, 0); font-family: tahoma, new york, times, serif; font-size: 16px; font-style: normal; background-color: transparent;"><span style="right: auto;">I use weights from a weight lifting set, the steel ones. They could go outside on a peg so to speak. The only problem is you want them at the bottom of the sub. That means hauling the sub unless you want to get wet. Maybe a slide system. I thought the same thing to put the air outside, that would kill my sleek and slippery-ness. :-) </span></div>

<div>Hatch closure from both sides deffenetly a good one. I would say adjustable exterior weights. I hate the idea on chucking weights on the floor and then sitting on them. I am torn between that and moving the hp air tanks to the exterior to allow alot more room on the inside.</div>
