Not to threadjack here, but Capt....what exactly did you mean by cascading through the colors?
When ever I color up I have a box of chips set aside for this in all the colors availible (i.e. coloring up T25 I would have black and purple availible) then when I get to the chip leader at each table who has already bought all the chips from the others there I can give them a few of each color instead of just all of one color (i.e. leader has purchased T500 in red (T5) from others at table I give him 8 green (T25) and 3 black (T100))
Does that sound like cascading?? I really have to admit my ignorance here (I understand the meaning of the word cascade (falling, etc) but not as you have used it here in the manner

)
