I find 1k chip stacks a little low.You can,t afford many mistakes.2500 is a good number.The big chip stacks of 5k like Cake had bad when they still had the blinds starting at the lowest level.As for the DOnks I don,t think they care one way or another about the Stack size they will still go ALL IN or overbet there hands which really makes it harder for the reast of the players when one player doubles up to 10k quickly.
