The strap buttons certainly aren't little! I had to replace them on my Brent Mason model because I couldn't get my strap on over them--and it was a PRS strap too! The problem wasn't just that the heads of the buttons were large and flat, but that the shaft was shorter than the strap is thick. I even tried taking the buttons off the guitar, putting them through the holes in the strap, and screwing them back on the guitar, and that didn't work either, so I replaced them with regular Dunlop buttons and everything's fine now. I did wind up using the original PRS screws to mount the Dunlop buttons, as the Dunlop screws were too short.
