I'm guessing this has been asked numerous time already, but the first threads that popped up in a search didn't really answer my question. I have been playing 45-65-85-105 forever. Feels perfect when tuned EADG. However, I play more and more in drop D (about half our set is tuned this way). When dropped to D, the 105 string feels a bit loose and flappy. The open D is much less "round and open" than the open E (sorry for the poor description, english is not my native language). Should I try replacing the lowest string with a 110 or a 115 string? What would the effect be when playing while tuned E? Am I risking to get the opposite effect? FWIW, I'm playing a Gibson Ripper.
