can u do the same tricks with dime and penny as scotch and soda

For the most part yes. However, with the SS you can put the Centavo and the Half into a persons hands and when they open their hands the Centavo changes to a quarter. You cannot do that same affect with the DP.

yes, but like chrisrkline said, you can't put the dime and penny in the specs hand and have them change. Go with s&s because dime and penny wears out to fast
