I've been using the RotoSound FM66 Funk Master set for the past several years on my 4 string. I know this set is lighter than most are used to(30,50,70,90), but I love them. I'll be upgrading to a 5 string Cirrus BXP at Christmas however, and have not been able to find an equivelant 5 string set. Any suggestions? I'm willing to consider other manufacturers, but would like to stick with 30,50,70,90 for the G,D,A and E strings. I'm considering using a 115 or 120 for the B string. Anyway, I need help finding mfrs that support 5 string sets this light. I'd be grateful for any suggestions, Eric.
