I have heard that a lot, and respect the opinions of others, but I have to try it on my own to learn. I'm playing with a small amount of money right now to see if I can make it work. I do believe, however, that trying to WIN one unit on a heavy favorite can kill you, but playing one unit is just as dangerous on any team. Same risk, but different reward...
Thanks for the advice, but check with me at the end of the season and I'll let you know how it's working for me
