is the skyline undersized ???
Never quite sure where the “official” / de facto dividing line is for when a yoyo in undersized - but at 50.5 mm diameter, it would certainly qualify as undersized by just about any standard. For comparison: Project 2 is 50 mm; dv888 50.1 mm; 888 50.39; wooly marmot 50.16.
ts like an 888 with the g5 h shape, so if you think the 888 is to small for u then yes.
