I've been lurking on these forums for a long time but never bothered to sign up until I saw this thread.
I am a huge fan of MMA and I bet on almost every UFC event.
I haven't checked out MMA Rats but I am a member on http://www.mmabettingtips.com and they are excellent. I pay $9.95 a month for all of their tips and I have won a lot of money because of them.
They've got a few good picks for UFC Fight Night 56 tonight. Hopefully I am going to win some cash because I made a loss last night.
