EDIT: Payout on CM is much better than MC for the last week. Was testing the waters and am going to stay

So in the interest of perhaps changing the subject off the reject rates (last couple hundred posts!) I was wondering something about pools in general.
The more Hash Power your pool has (for example CM has just gone from 1Gh earlier this week to 6Gh today) does it increase the overall profits for the miners within the pool.
I actually have no idea how the overall effect of having so much more hash power would have on your individual miners as whole...does it even make a difference after a certain point? Maybe someone can edumacate me on this considering this is probably the fastest growing pool right now I just wonder if we should applaud more users/bigger pool/ high hash or rather keep it quiet and hope it doesn't get to big?
