I’m always tempted by the recessed ones, but too chicken to do it.
They do look totally badass, much more attractive than straplocks that sit proud of the body. But A) if you lose your strap with the straplocks on it, or if your straplocks break, well, you're SOL; and B) yes, be very chicken: I had mine installed by one of the most respected pros in NYC and he still wound up drilling slightly off-center/out-of-round, and cracking some of the finish!
