My best shooting bow to date out of the 15 I own is a 56" Treadway Black Forrest. I also do not consider 60" to be short. Intermediate or as I say, normal....
I do own 64" traditional "Back to Basics" D style Treadway that is also a phenomenal shooter.
The 56" is just a perfect symphony for me at my 27" draw length. Perfect riser window, length, weight. It just plain shoots.
I recently built a 3 piece 66" longbow at 42lbs , 40 at my draw length and if my form is perfect, it will bust knocks, but with the lighter weight draw, my form errors result in left shots.
