A little background first 1. I hate thick wallets. Everyone I own is less thick than a say moto Razr. 2. Currently I am using a combination of a regular wallet with ID window as cash compartment or a 'money clip wallet' which I prefer for most day to day. 3. I dont really use cash, but I do always carry some with me 4. I am going to Las Vegas in may for a big convention. I am going to be dressed formal and then classy casual. 5. My problem with both of my current set up's is that even with minimal cards the regular style wallet is too big, but the money clip set up doesnt give me any room for business cards (which I really need to have on me for vegas) That said, I picked up ben sherman 'mini wallet' at TJ the other day. Its got an ID window, and plenty of room for both Credit and Business cards, (but no cash), while still being very slim ( slightly more robust than a 'card' wallet you might see). I was going to get a money clip to go along with this for my cash (which wont come out too much). Thoughts on my setup, comments on your own setup, and thoughts on a money clip (leather vs. metal).
