ok, my band sometimes plays in drop d, but when in drop d, the d is really flubby. like its just loose. if i use a 105 instead of a 100, the tension will change...correct? also, will i need to get a set up? also, im debating this whole flatwound thing. now, i kill normal roundwound strings within a few days, so i get elixirs. are flatwounds just going to be dead right out of the box? and will my acid sweat make them just sound even worse?
