			Man that's some beautiful work!
 Since we're giving advice, I recommend ballasting to the point where it is slightly negative with shaft in and slightly buoyant with shaft out.  As long as you have line attached the shaft will always keep the gun from floating away.  Still good practice to put your arm through the band after firing though.  Also the weight should go forward along the barrel.  I didn't put enough weight up front and my spear tip tries to float up while I am lining up a shot.  May be less of an issue with the shorter gun.
