YYF sold all its remaining stock of Throwbacks and Acrobats to Yoyoexpert.com (André Boulay). According to André, he has about 30 Acrobats and 20 Throwbacks left. Unfortunately, the Throwbacks are all in the display case so they cost $150. The Acrobats are $100 (even the inkblot design, I believe).
In Spain I discovered a design flaw about these tops. It was Sunday night and I went to the festival to see the awards and the final circus show. I put my Acrobat, a relatively small top, in a pocket just in case the need to throw a top came up, as it surely did. But when I tried to throw it I could not take all the string out of the top! I had the string stored inside but a knot had formed bigger than the hole! Of course, the stronger I pulled the tighter the knot became. So I ended up without a top to spin
I still need to figure out how to take the string out.
