To each their own I suppose. I prefer compact and sheet kydex sheaths are at least 1/2 in wider than injection molded. I guess this is only an issue if you (like me) like to wear the knife right behind the front pocket. Of course, LEOs and SARs may have other equipment already taking up that spot. As for horizontal carry, I'm kinda round. The only 10" flat spot on my belt is on my back and wouldn't be to comfortable in the truck. Back to the original question, the F1 runs around $100, get a custom sheath for around $50 and you're in business.
