How to add larger denominations earlier in a tourney

[Small Fry]

As the TD I add the larger chips into play whenever I get the chance. I start with 5, 25 and 100. At the end of round 3 the reds come off. Typically they're colored up to greens (25) and blacks (100) but if someone has a lot they might get a purple (500). The next color up isn't for another 6-7 rounds when the greens come off. But as players get eliminated the chips get consolidated and the blinds rise so there is less need for the greens. Throughout the rounds and during breaks I will pull greens and blacks from players and color up to purples or even yellows (1,000). I really don't have any set times where a color is introduced. And as already mentioned you need to make sure you don't pull too many as then players constantly need to make change for each other.

And, Since I agree with this so strongly I have mention it once again in this thread. Having a 5, 10, then 25 or 25, 50, 100 is just plain wrong.
