What's your hate? Difficulty in snapping them on, or retention on the belt?
I'm another holster collector and have been switching back from hybrids to all leather. I wear the Watch Six a lot for IWB, a leather slide for OWB, and actually just ordered a Milt Sparks 55BN for OWB carry. I really like all leather for 1911 carry, though if I carry a plastic gun, I still like the hybrids. All leather is just SO comfortable though - especially for IWB.
The snap loops are one of those things that, because everyone uses them, it's hard to find an alternative. Or at least, not a leather one. Here's a company that almost got away from the snapped loop, but really just moved the snap elsewhere.

I know the snaps are supposed to let you put on the holster on, or take it off, without moving the belt. I know that works for some people, somehow. For me, it makes a lot more sense to just leave the loops closed, and run my belt through them. So I'd rather not have snaps in the picture. A solid loop would work better for me.
Yeah, I know, I could get a custom maker to do whatever I wanted. It's just gets too expensive, at that point.
Pretty cool about the 55BN. Those have always looked like really nice holsters, to me. I actually got a holster like that for my XDs (not a Milt Sparks), but it just doesn't fit right on me. I don't know if it's because the guy had the angles/dimensions wrong, or if it's just too small of a gun to work right with that style of holster. The loop spacing conflicts with the belt loops on most of my trousers. But Milt Sparks knows what they're doing. Best of luck with yours.
