I recommend to watch Jeff MCbride's art of card manipulation series or Jeff Sheridan ( teacher of Jeff MCbride ) on his L&L series.
I use red Bee's for backpalming and I think there better then manipulation cards ( at least for me ).
Because manipulation cards are more difficult to hold cause there bridge size, but on the other hand they have a flesh colored back so people see them less behind your hand. Bee's are €3,50,- and manipulation cards are €14,99,- at least in Holland
so I would go for the Bee's.
