Skin and Syn are 2 VERY different routines, SKIN is a fantastically structured routine, but relies heavily on sheer suggestion. Ben does go over everything you need to know, but it will take a lot of trial and error to get right. When you get it down though, it's mindblowing.
My routine, first it uses 2 coins, both of which bend, again, you just need the required prebents, after that it can be done on the fly.
The 2 coins are used for very specific reasons which comprise layers to misdirect and cover up any moves or motions. It's simple, direct and you will ALWAYS gauge a positive response when you ask if they feel it bending. Of all the coin bends I've used and come up with, this is the one that stuck, when you perform it, you'll see why.
Best,
