Like Ben said go with the 66". I had a 64" and it was ok... but the 66" was alot smoother at my 30" draw. If your looking for an ultra short longbow and have a long draw, IMO the PLX is not the right bow for you. I belive it was designed to be a
L O N G B O W.
Just throwing this out there, you may want to take a look at Lost Creek Bows. I just got one and I am very impressed with it. It's only 58" but draws very smooth even to my 30" draw. It is as fast or faster than any of my recurves but, much quieter.
Good luck, Glen
