Update:
I picked up a bifold Fossil front pocket wallet a week ago or so. It's got the metal clip on the outside. So far, I've discovered a couple of hidden advantages:
1. It's small, so I just put in the most important cards. I feel liberated from my big wallet!
2. Front pocket carry is, so far, proving to be comfortable. My butt and back have been thanking me ever since I switched to front pocket wallet.
3. Perhaps most importantly: Previously, whenever I carred my endura in my front pocket, it would eventually turn sideways in my pocket, making me look as if I were in a perpetual state of arousal. When I saw people lookingl, I'd shrug my shoulders and apologetically explain that I'm Italian, and well, you know the Italians. However, with the front pocket wallet, I slip the endura in just behind the wallet, and the endura is held upright. It is extremely comfortable, and the two work well together to hold each other in place, at least in jeans. Haven't tried dockers yet.
The one downside is the typical money clip downside. I like how a wallet hides my money from people. With a money clip, everyone sees what you're carrying. I've solved this problem as follows: I arrange my money in the money clip in separate bundles. The singles are all folded together, then the 5s, etc. When I pull my wallet out, I keep it lether side up (money clip side down), so no one can see the money itself. I feel with my fingers for the denomination bundles I want, and pull just that out. I'm not sure if this routine will eventually get old.
