I would like to have some input from others here going with this route of carry. Specifically, what sort of carry method are you using... type of suspenders... type/brand of belt. I have been using Perry Ruf-n-Tuf for a while with a single ply 3/16" thick leather belt in a variety of carry methods... including AIWB, IWB/OWB Strong Side/Behind Hip.
My sticking points have been where the suspenders attach getting in the way of gear. I also do not tolerate much pressure on my abdomen so run the belt one hole looser than I'd like to... this causes problems with sagging and twisiting (mostly OWB). I will be getting a new belt soon as I don't have anything stiffer currently.
That being said, is there such thing as too stiff in this instance? I have looked at 5-Stitch Wilderness, Ares Aegis Enhanced, Milt Sparks 2-Ply, Custer Custom Leather 2-Ply, JRC (long waits sadly, seems like a great belt). My concern is also thickness of belt, as it seems approaching .25' (1/4") would not allow use of the clips for the suspenders on belt.
