Managed futures question

Hi All,
I'm an experienced trader in stocks and I'd like to diversify into leveraged markets like commodites, Forex etc. but I'm yet to develop a proven successful system.
I found this web site http://www.managedfutures.com.au/perform_entry.htm which shows performance history of various funds. I've never gone down the path of managed futures before so I was wondering if anyone had any suggestions, resources, links, advice etc. which might help.

Thanks

Have a look here. They specialize in Commodities. They also have a managed futures section. But, l think that min entry fee is 50K U.S.
