Anyone using these gauge of string? I'm looking at my options here as a way of tightening up the B on a 34" scale bass. DR offers a .135 in several styles, as does D'Addario and Ken Smith (up to .145). I'd like to know how folks like them. I did some research and found (per a D'Addario string tension chart, and a little math) that the .125 or .130 B's are usually several pounds lower in tension than the rest of the set. A .140 gets into the ballpark and .145 is pretty close to a match. Are these larger strings pretty decent? Ridiculous? Tough to play? Don't feel much different than the next size down? Looking for your experience/opinion. Thanks!
