Since nearly one year i play my T10.000 Tourneys with this breakdown:
16x25 16x100 16x500
That make some nice looking starting stacks.
We allow rebuys the first 4 rounds, so if a player rebuys, he gets 10x1000 and he can get change from the big stacks.
It works really well and all the guys like it.
Also it makes the players play more because they don´t feel like broke if they give away 5 chips.
Oh...i forgot to tell you about the breakdown of the set.
For 9 Players i have:
150x25 180x100 180x500 60x1000 20x5000 10x10.000
This is how they look like
