I think the whole “the FHZ sucks stock” is a little over played. There have been how many contests won on a stock FHZ? Yuuki won with one I know. Danny Severance was amazing with his! Spencer, Paul, and many others invented numerous tricks on a stock FHZ.
Many more, but the point is it’s not the yoyo that’s the problem. So many ways to play a FH, stock, dead stickers, only 1 sticker, sili recess, sticker recess, add weight rings, etc. May just be the best yoyo ever designed (and mod’d)
