If I can't find the right coated strings, I miiiigghht go back to Hard Rockin' Steels. The only other strings, to me, that sound and feel as good as these, are DR Lo-Riders. But, the DR's die much faster, and yet, LaBella seems to have a consistency problem, with some strings not being as bright as the others, fading faster, etc. DR is super-consistent, but has the drawback of what I just mentioned. If you get a good pack of LaBella's...LOOK OUT, they'll kill for a long time!
A 5-string is THE bass. Why? More bass.
