All of those mentioned above are great. I enjoy loophole's posts as well. If you are going to follow one of these guys, you're best bet is to find one that fits your style of gambling, (# of bets, underdogs/favorites, varying the size of your bets, etc.) and stick with that guy. If you are going to be handicapping your own games and are just looking for insight, everyone who posts here has valuable input.
Good Luck to you.
