I have several and like all of them. Milt Sparks and Bob Mernickle are two rigs that really stand out for me, and I do mean to someday have a "full dress" rig from El Paso Saddlery. My Mernickle rig, made for my engraved Vaquero, is my favorite BBQ setup - I'll take a picture when I get home, if I remember.
While I do still use them for "outdoorsman" kind of stuff, though, I've gotten away from them for EDC since discovering the adjustable "ratchet" belts from places like Nexbelt. They match "business dress" much better than do more traditional belts, and I really appreciate being able to easily and precisely adjust them between sitting, standing, "before and after" meals, etc. Not a lot of "pride of ownership, of course...
