Im with Ian. Stick with magic for now, rather than trying to branch out as a mentalist.
That's not to say that you shouldnt introduce some mental magic into your routine, Its just that you will find it much easier to routine the stuff with what you already do, if you go Mental lite.
Simple predictions, and drawing duplications, will serve you better than robbing someone of the power to stand up, or remember things.
so, invest in a decent peek wallet,( of which there are many) and if you dont have one already, do, do get a good quality finger chopper.
trust me, there is nothing people like more than having their finger chopped. I guarentee 100% that with a good prop, and a great routine, you will be doing gigs where you hardly touch the cards.

you're like Yoda.you dont say much, but what you do say is worth listening to....
