I would happily test some string, film a good review, and post it on youtube and yoyoexpert.
Hey guys, I have these giant, ten pound gold bars that I need tested out for everyday use. Anyone willing to?
But really, proactively trying to find string to test is an interesting strategy.
Ok i have strings that i would like someone to test BUT… you have you film a video of yourself hopping on one foot for a minute. ;D
