Alright, I am still not sure what I will end up doing now. The ski I am looking at already has the light weight TDR waterbox, and I will run a 2.3 gal kart tank, so that should help a little with the nose dive problem. I will also be running a 7lb battery, and with the little 650 motor the boat should be pretty light.... Just gotta figure out if Tom's tubbies will do a good enough job to keep the nose from going down, or if I need to do the nose mod also, or just do the nose mod wich sounds pretty good without tubbies...... I may just do the nose job myself.... foam is pretty easy to shap, and I have a alright eye for lines. chit, I realy dont know what to do now. lol
