I've been hitting with an M-fil 300 strung with Cyberflash 17 (1.20) @ 58#. While the spin and durability is nice, it feels stiff and I would like more power. What string/tension should I go for next? Locally, I can get Prince Synthetic Gut. Would this be what I'm looking for? If I buy from TW, I wouldn't want to spend more than $10 for string. Any suggestions or recommendations would be great.
