That is logical. If Schallers work for you, that consistency is important.
Gotta say though: I used Schallers for many years, but while better than no lock, they were a pain point -- requiring constant maintenance, especially back in my days of heavy metal posing. Then around Y2K I got a bass with Dunlop Dual Design locks. I was skeptical, but discovered that they just work... and no constant retightening of that hex nut because there isn't one! Dunlop locks can be tricky to install, especially on thick leather straps that aren't pre-drilled for locks (fortunately many strap manufacturers now offer this option), but once they're on, they've been worry free. The only issue I've had was very early on: I didn't insert the lock all the way into the button so it popped out (no harm done). Lesson learned, I've had zero issues since, and now all my basses and straps have Dunlop Dual Designs.
Seems weird to rave about a strap lock, but yeah, it's that big a deal to me.
