I feel i have gotten good enough to start posting reviews of yoyos, but seeing as how that and string are already cornered markets, i figured i would do reviews on the next available thing: response systems!
How i would review the pads:
I would install them in 2 designated yoyos, the C3 Vanitas as my light yoyo and the YYR Valkyrie as my heavy yoyo. I would play with the yoyos and record their qualities over the first hour, recording how they were breaking in, both in relaxed play and strenuous play (strenuous= tricks that are more wearing on pads like gyroflops). I would then record how the pads felt doing the exact same tricks after around 12 hours worth of play after break-in had been accomplished. All in all donations would require 4 pads (2 sets). If you are curious about donating let me know! If not, no worries!
