Pat, I always made my BBO bows around 60 to 62 at the most. This is my first try at 66 inches, and I'll never make a shorter bow now:) This bow is the best shooting bow I have ever made. Very quiet, very fast, and very accurate. And it draws so smooth. And I will add, with the longer limbs, it just seemed so much easier to tiller.
Spent 5 hours in the Bow Shop tonight, tillering another one just like it. Seems the more I make, the more I learn and the better they come out. And I have another 66 incher waiting in the drying box:)
