Dont know if you guys have seen the Ribtek heads. Made in Australia, only a buck 65 Australian, available from 110g to 190g and tough as old boots.

I shot a few into hard trees the other day, dug them out with an axe and they were still fine to use again. Slightly blunted but not at all bent. Certainly makes makes mechanicals and and multi bladed heads look like single use items.

A few nice trophies and non fancy looking archers on the site.
