What are your opinions on the shadow coins / chink-a-chink routines? Personally, I think it is one of the most magical looking effects you can do with coins. Fast paced and insanely visual. I'm looking for a good source to learn shadow coins (or a chink-a-chink) routine. I don't really like the four coin variations and I don't mind incorporating a gimmick. Any recommendations? I've heard good things about Ammar's Easy to Master Money Miracles vol. 2.
