Ideal Denominations for Tournament Poker Set

Hi,

I run a small league and am in the process of having some custom chips made up.

My question relates to which denominations will be the optimal amount taking into consideration tournament play and my budget to purchase said chips.

Most of the tournaments I have played in my life (at casinos and in pubs) have something similar to this:

Example Start Stack:
- x 100 denomination chip = 500
-3 x 500 denomination chip = 1,500
-3 x 1,000 denomination chip = 3,000
-4 x 5,000 denomination chip = 20,000
-0 x 25,000 denomination chip
Total Start stack 25,000 (15 No. chips)

What I do not like about this set up is that the 500 and 1000 denominations are too close to one another.
I read somewhere awhile ago that the ideal denomination structure is where each chip is around 4 to 5 times larger than the previous lower one - which makes sense to me.

In such case I want to structure my new set & starting stack as follows:

10 x 100 denomination = 1,000
8 x 500 denomination = 4,000
8 x 2,500 denomination = 20,000
0 x 10,000 denomination
0 x 50,000 denomination
Total Start Stack = 25,000 (26 No. chips)

This kind of set up seems ideal to me.
One, more physical chips in the starting stack makes the general player happier.
Two, there is no wasted denomination. Each one is 4 or 5 times larger than the previous one.

However as I have never seen anything akin to this set up (even in the WSOP in Vegas) I am worried that I am missing something.

Hence my writing to this forum before I go ahead and spend some money.

Yours comments will be appreciated.

Regards

Greg
