Do you need tip overlays to shoot fast flight or is that just a myth?
You might want to put one on an unbacked ERC.....
sorry Pearly
Seriously.....a tear drop shaped nock in a hardwood eg. osage, hickory, oak etc would be fine, softer bow woods eg. walnut, ERC, yew etc would be better to have an overlay for any string type, FF or B50. IMO
