You will not believe this!!! I internally weighted my speedmaker :o Ill put up pics later and describe too!!! i used some rubber bracelets and put them under the caps of my yoyo, added some weight, gives me about 1 minute long spins with enough spin to bind still, which is an improvement over the 35-45 second spins before!!!
Nice mod. SpeedMakers are great yoyos. I play mine stock though.
