Hi Drakven,
I'm in the middle of trying to create a purely mentalism table hopping act right now. (Cos it's easier to get work in restaurants and after Blackpool i am soooo sooo poor.

)
Some of the things I'm using are:
Osterlind deck routines
Bank night
erm Some Andy Nyman Drawing dupe / psychometry routine i can't
remember the name of from "Short Punchy & mental Notes"
The esp card trick with 2 sets of 5, spectator putting down a card after you, then all math, (again forgot the name)
a coin based symbol prediction routine from jay sankeys 22 blows (now what was it's name again??:) )
coin in hand when someone annoying asks for stuff "What that Derren bloke does on the telly"
little bit of muscle reading on an unseen choice of table item
my long lost point being that there are a good variety of effects not using cards that can be used as table mentalism, if you should choose to listen to those who don't like mixing genres, I'm with them, but I'm pro choice, vive le difference!.
