I have been watching this thread with interest as I awaiting the arrival of my whoopee slings (and some other cool gear from AHE).
I scored some arrow shafts from a mate at work that I’ll give a go – all be it hanging ever so close to the ground.
I measured them on the weekend and they are aluminum, wall wide of .7mm and shaft diameter of 1cm. (sorry about the metric numbers guys).
I’ll give you a update, should only be days away.. Surly.. Is that the mail man?
