I know most people like the thick, chunky leather straps but I'm with you. When I switched to a thinner, tapered strap it looked remarkably more refined.

In the review the straps are 24-24 but if you check on EBAY for "Bob Marino" you will see they have a 24-22 offering.

I'm partial to this one:

The dark edges contrast well with the light leather and the keepers are nice and slim.
