Thanks Badger, Halfeye and Medicinewheel.
Hrothgar and El-D, Cedar Elm makes a good bow and it's usually a creek bottom tree in Texas, like Hackberry. But hard to find any that's knot-free.
Kviljo, I plan on thinning the outer limbs more; and maybe around the big ol' knot.
MaKenzie I'll send it to you if you're serious...but I may not finish it for a week or two.
