Also, by chance have you ever tried Isospeed Professional? I was wondering how this string compares.
A buddy of mine who plays at a higher level is using the Isospeed (arm developed some tenderness) and loves it. I was thinking about trying it out....but the Isospeed gets SHREDDED in short order, which is a serious turnoff. (He shreds it in a day, which means I will probably shred it in 2). This stuff sounds like it might be similar in performance, but much more durable.
