<div><font size="3">I considered a slide system for exterior weights, but I couldn't come up with anything I like for adding weight, and it was even worse for removing weight.  I reserved the space under each of the two seats (tandem) for the removable weights.</font></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>
