Thanks for your interest W.A. I haven't found any shorter than 28.5 yet. Did learn from Bow Tech today tho that any dealer should be willing to change those no problem. Also have been comparing draw length on the cams to lengths on last years Pro 40 duallys and some others I have, and am finding these new ones to run about one half in. shorter. So I may be ok after all. Will have to shoot this one for a bit. If I change now, it wouldn't be for more than 1/2 in shorter. In other words, the E-5 cam.at 28 in. On the duallys, I've been shooting both the 27.5 and the 28. Hard for me to part with those bows, and I may not. Will keep you in mind.
