What halfouts are you using with them?
Here's the GT factory aluminum half-out after hitting a cow elk broadside. She was recovered, hit a single rib on the way in, arrow didn't exit and fell out as she ran.
Not mine, a friend I was with.

Arrow got snapped in half as she ran. However no damage at the insert end, that angle you see is all bend in the shank of the half-out. Long broadheads put a lot of leverage on those points.
I can't remember if those were the .204 or .166 shafts. Likely was the .204, either shaft size has the same issue. I wouldn't be using the GT aluminum components.
I have seen damaged SS half outs as well. I think the whole halfout component system just has too many pitfalls. Go with a hit system in a .204 if you want smaller diameter. Or a proprietary system from a few of the broadhead manufacturers.
