I am gearing up for the winter version of the Garage Poker Tour. I ran a successful tournament for 11 weeks during the summer and at the players request I am reworking the starting stacks for the TOC to accomodate a T25K plaque...seen here

Yeah they are pretty sweet aren't they....home made out of aluminum bars. They have never seen actual play, and it is sad...
During the summer league the regular season events were T5,000. and the TOC was T10K start and added 1K of chips per point earned. The average starting stack was close to T22K, and there were 7 players. I plan on having at least 9 for the TOC this season.
As you can see that format won't work if I am going to incorporate these plaques into my TOC.
My question to you fine folks is...Do you have a suggestion for a MINIMUM starting stack that makes it feasible to incorporate a single T25,000 plaque. My first thought is 100,000, but that seems a little low...150,000? 200,000?
I say feasible only because I assume you know as well as I do that I could include the 25K into almost any breakdown, but then it wouldn't actually work in play because it would constantly have to be changed for smaller denoms between players. (hopefully that came out like I wanted it to)
Any thoughts/reactions considering this minor dilema will be thoroughly chewed on for several days before making a decision!
Thanks in advance,
Captn
PS: The denoms I have availble to go along with the starting stack are 500's, 1000's, 5,000's, and 10,000's and at the maximum there will be 10 players.
