I need to talk with Jack. It is more about what weight my existing riser can handle.
I am hoping 70#. If so, that will be plenty. His bows are just great.
The only bow I have shot that is comparable is the Border Black Douglas Swift. I can get heavier limbs on the Border, too.
The difference between the two for me is; the grip. I have small hands and the KS grip is smaller. The Border has a great grip but it is just a shade bigger than the KS.
My Border is 62" 55# at 28". Because of the carbon Hex IV limbs it shoots like a really heavy bow. Major league speed and hitting power. Zero Hand shock. Wicked bow.
Being that I am Scottish, having a bow made in Scotland is very sweet.
