Basic ingame strategy - Fezzik?

Basic ingame strategy - Fezzik? I have a couple og outs (pinny, bet365, maybe others) that offers pretty good ingame wagering for NFL and NCAA. Is there some basic rules or tips I should stick to? Im basically just Trying to find out how much Lines move for every Down (which is a lot at 365 and not that much at pinny?). I have allready found out, how addictive this monster Can be :-) I have also found out the hard way to stay away from garbage time :-) With The Right strategy however, I am sure there Are Lots of +EV bets and middle opportunities to be found.
It's complicated........BUT.......DO THIS 1. Try to watch THE MOST OBSCURE CHANNEL game that has live wagering. The ESPN and ABC/CBS/etc games will have 'everyone' wathcing it. MUCH MORE LIKELY you will find a spot where the market is asleep on ESPNU, etc. So.....in the NFL..........I'd watch Minny/Jax and if Percy Harvin gets his leg rolled like a Preztel, doubt the odds will correctly adjust for it........vs. if Tony Romos ribs get Crushed, $$$ will POUR in on Gmen and UN IMMEDIATEDLY......... 2. DO ONE GAME ONLY . REPEAT. ONE ONLY. Makes it MUCH MUCH EASIER to pick off the bad lines.
