Have tried the following strings at the following tensions:
Lux 4G S 16L @58 and 53 - low powered, good spin, lasted 80 minutes each
Lux ALU @53 and 51 - better power and spin, lasted only 40 minutes each
Lux Original Rough 16 @ 51 - good power but less spin (suprisingly), lasted 90 minutes.
Trying Polystar Energy 16 tonight and will be trying Lux 4G S 15 this weekend.
