I was actually thinking of moving from the 1/4" Tru-Peep to the G5 Max Hunter or whatever they call it which is 5/16".
I shoot a Spot-Hogg Real Deal with the large pin guard and want the biggest peep I can find that is of the Tru-Peep style.

I heard a couple whispers here and there about them collapsing too? I generally serve above and below and around the middle so I don't want fold the thing over........I imagine the largest diameter would be most prone to warping/ collapsing?

Also has anyone heard any issues with cutting string strands?
