If you want one arrow for different bows, especially at different draw weights, the AD's are the way to go. I shoot the Lite's, Trad's, and Hammerheads from all my bow's, weight's ranging from 45# to 56@26, with Risers also cut different to center. I just change point weights to get the arrow weight I want. Which one you choose depends on how heavy an arrow you like, but I agree with Chris and Elk on the Lite's, they keep me around 10-11 gpp. I'm sure all our sponsor's that carry them are first class and can advise you over the phone. I only have experience with Ted Fry at Raptor Archery, I gave him a call and he set me up with just what I needed.
