I have had two whisperstiks, they are really quiet bows and smooth drawing, and they seem to have a very good cast.
I just ordered my third whisperstiks bow from JD, about three weeks ago, he said it would be here about the end of November. The wood I chose for the limbs are bamboo core with hickory overlay on front and back with mature grain. JD is put a special leather on it. He didn't say what, but I sent him a photo of a quiver that Don( E F Q ) made for me.
He's a great person to work with, he will get exactly what you want. I gave up my other two whisperstiks, and couldn't stand it ! So I am having one made for my specific needs. It is a lower poundage 45# but J.D. said the woods I've picked out will produce good performance from 45# @ 29". JD recommended I go with a 58", I originally wanted to 60" and he explained why the 58" would be better.
You most definitely can't go wrong with the whisperstiks, when I ordered mine, I told him
" there's no sense owning anything but the best"
He does a great job, and is a fine craftsman.
