I'm buying an agile relatively soon and I'm looking for a good string set. I Want a lot of tension in standard and somewhat average tension a half step down. I play a lot of faster material and would like my strings to have a lot of tightness and sustain, especially on the low b and f, in standard AND a half step without using something crazy like a 90 gauge etc. Id like a pretty balanced set but I do like my low b a "little" loose, not a ton. For example I'm using the ernie ball 10-74 set right now. Its a pretty unbalanced set but my only problem is with the low b and low f really. I would like to try circle K strings. Somewhere around the 10-80 range. Suggestions would be awesome.
