Any body play with these? I started playing with a band that does mostly D standard tuning and occasionally drop C. Is the .111 going to cut the mustard for a C string? They describe the strings as having larger cores for added tension but seems like the gauges are the same as the old M70 stainless steel set. Other options would be DR drop tuning, Dunlop heavy cores, The heavier set of D'addario balanced tension might also work exl160BT, the long heavy boomers with the .115 and Kalium. I was using Pro Steels but the .110 felt a bit loose at C. They do make a .120 string but I'm worried that might be too tight tuned to D. Thoughts?
