I have an 05 Saber with the Tru Arc + cam. the limbs are 6H, shoot 52.5, split is 34.5 and control is 38". On your cam chart, it is only showing two draw lengths for the 6H limbs at 65lbs. Now I happen to fall under those 2 at 28.5 inches, but this doesn't mean I can't get the other draws does it?

I could be wrong on this but I also have a 05 Saber. I currently have 7H limbs and my draw is set to D. I think the poundage migh vary a little when you change DL's but I am not 100% sure. I am sure you are still able to change to all the other draw lengths. I have with no problems. Hopefully one of the Martin Techs can pipe in and give a definite.
BTW how do you like your Saber?
