There fine on most hard woods but I had 2 ,one crack ,one break off white wood bows (hickory,slippery elm).
There is on benfit ,other that makeing the tips lighter to dedue hand shock.
But there's other ways of keeping the right tip weight other than pin nocks to dedue hand shock. Good tillering makeing sure one limb dos'nt finish before the other, keeping the last 4 inch of your tip light enough ,putyour tips don't bend..
I'm not saying don't use them by all means build bows the ways you like. But I keep them on the stout side. Or you might be shorting a bow.
