I was tinkering and looking at some Easton Deep Six 340 arrows today and discovered they fit perfect inside GT 7595 shafts.
So has anyone used them as internal footings for GTs or as super double shafted cape buffalo arrows?
My curiosity was killing me, but you should have seen the look on the face of the wheelie prostaffer!  

That's an expensive weight tube!

I was not thinking weight tube, but strength modification in place of the wooden internal footings that rattled upon release.
