Has anyone else done this mod with their Spinstar or ‘Play YoYo’ Collection? Replaced the transaxle with a Loop 720 axle, SPEC XS bearing and green 720 spacers (basically USA 720 guts). This Spinstar happens to be Zipline branded and laced with [kot-n]. STM for days with this setup. Great modern responsive plastic alternative, surprise @yyfben2.deactivated hasn’t issued these as Spinstar GTs. This was what I was talking about @AKYOYOMIKE
