Since Magneto can sense metal, the pulley components can't have metal components or bearings.
Probably not fiberglass (I haven't done sporting archery for a loooooooonnnnng time. Like 17 years). But I do know that there are composite bow bodies that don't need metallic components to function and still have the penetrating power of small arms rifles.
There aren't any bearings... though I'm fairly sure you could customise a compound to have its cams made from a ceramic/polymer composite. As for the riser... same deal, though the limbs would have to be recurved, otherwise I don't think it'd be able to take the strain. It's the release aid I'm wondering about... 'cos the rest of the array doesn't
need to be metal, it's just cheaper (like a couple grand cheaper to have cast risers).
Anyway, former compound archer whose back is a bit fucked atm... greetings, fellow former toxophilus (that is, of course, provided you enjoyed it) =P
Still, definitely, have a bow with sufficient weight and high percentage letoff, he wouldn't know what hit him (armour or otherwise). And all that would be heard of the shot is a soft 'thunk'. One guy I knew had a bow (35kg wall weight) that was literally just a 'click' at loudest.
