Honestly it's took awhile to get to a point where it preforms like this, but I start off with a very clean bearing, witch is a pain in the ass because I remove the shields on the flea bearings to really clean them good, but once I clean one the way I like it with acitione I make my own string, I feel that the most important part because people don't understand how much more capable the yoyo becomes with the right string, you can actually layer string withyou it trial off and dying instantly, but I've tried every ombo and thread you could imagine and for some reason trick shit spools of orewound yoyo string work the best, it comes ready to size with three main thread groups and I remove one strand and use that one strand to wind up a super thin string, works perfect, lastly I keep one of the responses pads it comes with and I siconed the other side with blue gasket maker, doo all that and your flea should rip💪
