Re: G string blues.......
2 Things:
1) The knife edges on the trem can definitely be sharpened and polished to better-then-new condition. No need to ditch it or block it if you like and use the trem;
2) You description tells me that your problem is absolutely the nut (when you bend the string it pulls some string through the nut toward the saddle and binds the string when you release the pull. This leaves the string sounding flat. When you use your trem it releases some tension on the string allowing it to go through the nut toward the tuner. The nut binds the string and when the trem is released there is more tension on the string between the nut and saddle and therefore the string sounds sharp). I don't care if you've replaced it 10 times, the problem is still the same and it MAY just be coincidence that it was the G string both times. You should NOT use any kind of lubricant on an LSR roller nut...only compressed air to blow it clean. The lube will collect dust and other particulate matter that will grind the heck out of the rollers and gum it up causing the rollers to freeze up and pinch the string.
If it were me, I'd leave the saddles alone and replace the nut with a fixed bone nut. Make sure each groove is filed to the perfect size and shape with a widening taper and getting deeper toward the tuner. If done properly, the only part of the nut that touches the string should be a very small "U" shaped edge next to the fretboard. The rest of the groove in the nut should not touch the string.
