One question...
Do you break a string often on your electric?
I mean... do you play whacking like Jimmy Hendrix?? :P
I've never broke one on mine (and i've tried, really)
But on the acoustic they're just like butter strings... the break in a couple of weeks
i've got a locking nut for the floyd rose trem, but I've just added the lock pieces after a year of playing without them and it stays in-tune a little longer, but not much. The advantage I see on having the lock is to tune with the micro-tuning pegs instead of the tuners... they're far more accurate to me
Something's wrong if you're breaking strings often on your acoustic. Are they breaking near the tuning pegs? A common problem is that the strings are seizing in the nut slots and not sliding freely as you tune. If you ever notice that you're turning the peg but the pitch isn't going up, that's what's happening. Keep turning the peg and all the motion is being taken up by stretching the short length of string between the nut and peg, and it'll stretch and break. Lift up on the string above the nut to release the tension. Another sign of this is the string suddenly "pinging" as you tune it. Next time, try lubricating the slot in the nut. Many folks recommend graphite, and a soft pencil's a good way to apply it. I've had success with various oils, greases and waxes. Eventually the slot tends to wear in so it doesn't catch the string.
