I'm shooting a 12 year old XI Demon. (a bow which was pretty much obsolete when i bought it)
It still has it's original string even. Most of the strands are still there. heh heh (it's a stupid size and I'm too lazy to figure out how to order a new one)

Still, it kills stuff if I do my part.

I have a 'back-up' compound which i use for bowfishing. It's an Astro Stinger which I bought in 1985. I think that bow is made out of cast iron and truck leaf springs. If I hold the string and hold the bow horizontal....it practically draws itself. ha ha

Then there's my 1970's recurve.
