OP,, Tnx for posting the chart, but I hate it, durability/performance ?!? Wtf.. (so much can be included/misinterpreted with 2 words). If I saw this chart, I would not waste my time trying to understand it, I would take a free pack of the string and find out for myself, if string was not free, I would look elsewhere
Im lazy, I want a chart to be easy and quick to understand,
im having trouble finding the power and spin on that chart..
Heres my experience with yonex poly strings on that list:
Ive tried poly.tour fire and thought it was a slick, power was high, not stiff., I cut it early, lack of spin/excessive power turned me off from it, i played great the first day though.
ive tried poly.tour.pro, not as slick, spin was low, power was LOW, not harsh, cut it out early, hated the low power.. liked the color
