Gold Tip arrows are famously tough as nails and offer nice components. I shot 400 spine ultralights for years and they routinely survived misses on 3D courses (glancing off rocks, embedding in trees) and went through deer and never broke. I've only had 4 break ever (that I can remember, besides robin hoods before I switched to pin nocks): 1 spine shot, follow up to first spine shot where arrow pinned deer to the ground and the deer rolled on arrow (so broke 2 in one day), skull shot (don't ask), and once my target fell over at an angle and one arrow cut another in half because I was too lazy to go set my target upright/pull arrow. I shot 340 spine ultralights for 2 years with zero breakages.
I have Gold Tips for my recurve that are 15 years old and fine.
I'll be moving to 340 spine hunters this year, and expect those to be tougher than cockroaches.
EDIT: Just saw your other comment. Gold Tip offers all sorts of factory heavy inserts and also weights that screw into the back of the inserts to add weight. I think you could make a nice arrow without all those mods and only using factory components.
