Not so sure about that...do a search here. Oliver (senmen) had issues with them wearing out after a few playings to the point that he persued it with the German legal system. I have several sets I bought off Ebay for around $50/set, but I haven't tried them mainly due to Ollie's experience.
Apparently, the Optima strings are not the Maxima versions JAE used, despite the advertising hype.
Buyer beware.
