I just went through the boxes in my closet and I found this $2 Yo that I bought 3 or 4 years ago from a dollar store: It was one of those (Imperial Style) spring loaded auto-return Yomega rip-offs.
Curious to how much it would let me get away with, I threw a poly string on it and started messing around. I managed to get it to sleep for 12 or so seconds and went through the usual dog walking and craddle rocking. I tried a trapeeze, and no dice. The force of the breakaway actually killed the Yo.
I tried a split bottom mount and it actually worked quite well. I was suprised how easy it was to land it with such a small gap. I returned it to my hand and went for the whole shabang!
I threw the strongest sleeper I could, landed another split bottom, put in some finger work and BAM. I pulled off a no-holds-barred Split the Atom on a $2 Yo. ;D ;D ;D
Point is kiddies, you dont need an $80 Yo to have fun (I still love my DM more of course.)
