I'm looking for some heavier strings for my P-bass. My current guage is 45-105 (Ernie Ball Slinky) and I like them. I narrowed my choices down to 3, and those are Ernie Ball Power Slinky, GHS heavy Bass boomers, and D'Addario heavy roundwounds. I've heard either very good or very bad things about GHS. What do you think? Should I stick with the Ernies or experiment? If so, what should i get? Thanks alot.
