Tecnifibre NRG. French made multifilament. Available in both 16 and 17 gauge. One of the best synthetics out there. If you want performance, definitely worth a try.

Tecnifibre 505 HPR 17 Racquetball. Hi performance string for players seeking the ultimate in power and comfort.

$28

Tecnifibre X-One Biphase: I am carrying this in both 16 and 17 ga. Not quite as powerful as NRG but still comfort oriented. Holds tension pretty well for a coreless multifilament.
