I'm looking for new strings to address several problems I'm having lately such as pain in my hands and several dead spots in my bass. I play a new 4003 RIC, use a pick going from light playing to hard both. Play a lot of double stops and bends. Rock music, punk, noise rock stuff. I hated the stock RIC strings that came with the bass, loved Ernie Ball power slinkies, especially after they died down a bit and currently have Dean Markley blue steels 50-105 set that I like just fine though they're a bit stiffer than the EBs were. I'd like to stay with either a 45, 65, 85, 105 or 50, 70, 85, 105 set. I'm looking at either the sunbeams, hi beams or fat beams. Really leaning towards a round core to see if it makes a big difference in feel. I was favoring the sunbeams but I haven't seen anyone mention them for a hard rock type of setting. Will they sound good playing double stops?
