So err.. gotta ask.. why did you buy a ton of packets of the same string you bought a ton of reels of?
Clearly you misunderstood the concept of double-pulling the string. You don't need to actually pull two strings!! --- I recently purchased 3 km from my local supplier, who just had received 40 km Yonex strings. I wonder how a single 40 km reel would look like, because with all the plastic, wrapping and cardboard boxes it sure take up some space! Btw. that red Zymax 65 was just a nice string. I have exactly one set left on my last roll... Next "red string" will probably be the Li-Ning No.1. You always need to have one red string in your arsenal, and I can't get BG80 red here, and I think Ultimax is too niche a string to carry a reel of, just for the color. (said the guy who already have a reel of UM in Lime Green)...
