High mass is there as it will have my trademark "cuttlefish' design...wt shouldn't be a problem just some trial and error with some ducktape and egg sinkers...recoil is not too much a concern (comparitively -american guns- speaking) as I will try to bring the bands as high up (read as much inline) with the actual shaft (thus the lam build up for the enclosed track), then a gain a little wt towards the back might do wonders, but that might complicate this balance you speak of Fox....
hmmm interesting I would have never thought....again pardon my ignorance...my euro exp. is very limited (in guns spago, in guns:inlove)barrel 28mm carbon guns are far more buoyant than a solid teak gun
