It depends on what your definition or expectations are for "durable". I shoot 70+lbs at 32.5"+ draw so "durability" is right up there at the top of my list with consistency and accuracy. I expect my arrows to survive hitting rocks, gravel, etc after passing through grouse, or any other game. I expect the same if I were to miss or shoot through a 3D target.
So given that.....I haven't found a regular diameter arrow that survives that every time. But I've been using the .204" ID arrows for about two decades with pretty good results. The smaller diameter arrows generally have thicker side walls for better durability. But I also prefer weaved carbon arrow shafts because they have proven to be the most durable for me.
I always use HIT inserts in my arrows, and have never used collars because from my experience I just haven't had a need to. I also prefer the streamlined looks and feel of an arrow without a collar.
So far the toughest arrows I've used are (all weaved carbon):
1. Trophy Ridge Crush 300's - discontinued for quite some time now, but by far the toughest arrows I've had.
2. Sirius Apollo's - tough arrows, but I never could get them to shoot as accurate as I'd like.
3. Victory RIP TKO's - what I currently use. Been using these for four years and haven't broken one yet.
[mention]Mighty Mouse [/mention] summed it up pretty well. I’ve also had great luck over the years with axis (5mm) shafts with HIT brass inserts, sans collars.
If you’re going 4mm, the only thing durable is going to be a glue in or deep six IMO. Half outs just suck, period.
Axis strikes great balance of price and durability. The value to performance scale really starts sliding beyond that. 6.5 mm shafts with brass inserts are tough to beat for the price. You can build 3-4 dozen for the price of equally tough 4mm shafts.
Gold Tip(GT) Hunters or if you want to spend more money, the GT Hunter XTs. I’ve been using them for over a decade and have seen no reason to change. I’ve killed a buck with the same arrow the last 3 seasons. All I do is clean the blood and dirt of it and change the blades on my broadheads.
I guess if the standards cost half as much you could afford twice as many arrows, so if they are slightly less durable who cares. It seems like there is a bit of a tipping point between cost and durability between some of the options.. inevitably I will send one into something way to hard or lose it then BAM 30- 40 bucks down the drain.. I suck at shooting in the wind so any misses that I have I doubt can be attributed to wind drift. Anyways thanks for the responses good to hear folks experiences!
