I’ve shot the 55 grain titanium half outs. They’re actually really tough, but they’re still a half out at the end of the day. Hard angled impacts will bend them, or you’ll have a sidewall blowout.
Supposedly the new aluminum 50 grain ones that comes stock with these has a little lip on it that goes over the shaft a touch. This should help with durability for sure.
I’m going to be doing a deep six build with these using Iron Will components. Even though the deep six threads aren’t as strong as 8-32, I think this will be the most durable using the IW system. I’ve learned my lesson with outserts, I’ve bent too many on hard hits that I don’t think I would’ve bent using a HIT system. Outserts just put a ton of leverage on the end of the arrow, it’s only a matter of time before you bend it.
Ethics all stainless steel would be another great option. Probably the strongest, but I can’t afford to put 250+ grains up front on my builds.
