I'm hoping to get one of the sluggers that I coach to try out a set of Tourna Poly Black 7 in 16 gauge. He's been using RPM Blast for a bit, but I've found some feedback here from other Black 7 users who also preferred this string to RPM Blast.
Since the Tourna Poly is a lot cheaper, I'm curious to know how this stuff compares - I'll be stringing a lot this summer and since I don't use poly myself, any samplings like this are helpful for me. Gotta stock up soon.
I'll hopefully have some results to share here soon.
