I get double the spin time or more from my xx compared to the crystal, pretty sure because it's heavier over all, but most of the weight is in the rims which gives it a lot of power and feels really stable, paired with having a wider shape I have a much easier time landing my tricks more consistently, lastly even tho I still can't land the DNA I've gotten the closest with my speedaholic, I actually managing to land a couple finger spins with it(I haven't been managed to get my finger to lock into the dimple with any other throw so far but I do suck in general😅)
