y-factor,campfire, and beysick

MY preferences are 50.5 mm and below, any shape, or response. In your opinion which should i get

Campfire def better player than all the others

umm, not really. In play, the Y-factor is about as good as it gets.
Well, beysick is the biggest, being 52mm, the Y-factor is in the middle, being at 50.40mm, and the campfire is the smallest, being at 48mm. So all you really have to do is pick your Fav weight and shape, and you have the yoyo to get.
