Just one tip on changing out the inserts. My Wings have the kevlar end caps and if you drop one in there it's a bitch to retrieve since the capscrews are stainless steel and therefore non-magnetic. I replaced mine with standard black steel capscrews and can now get them out easily with a magnet. FWIW.
