Oz pretty much nailed it, especially when you get that one person at a game who ruins the cards by bending the shit out of them as soon as you open a new deck of non plastic cards.
Have heard the copag's are good, but never used them. I do have two decks of the pokerstars cards though I got one time, and those are nice .... so you could always probably look at getting them through pokerstars via fpps
I train dealers for casinos. The cards that I use, and the cards that the WSOP will be using again this year is Copag. Bridge size, large index. They come in 2 pack set ups. Get a couple of set ups. Don't forget some bottom cards too.
