Kevin: Sorry I don't agree but have to say this.
I think its wise to look towards the sites with the most success and emulate their good points, especially for a new site with quite a bit of competition out there for membership money.
The most successful tournament systems I have seen is Cases leagues (which offers a variety of formats and is used by most of the online gaming sites for all games) and IYT neither of them use S-B, both have over 1,000,000 members.
If players don't like something then they won't support it in the long term. And it is finding what makes people the happiest which brings in the money. :-)
