search google, and youtube, or www.lacrosseforums.com. i learned everything i know about faceoffs from youtube(kinda sad, but whatever). the primary move in the midwest - especially wisconsin - is the clamp. if you can beat the clamp, or if you have the harder/better/faster/strongest clamp, you're golden. but it's always a good idea to have more than one move... generally the jump beats a clamp, a lazer/rake beats a jump, and a clamp beats the lazer/rake, kinda like rock/paper/skizzors(dont care that it's an alternative spelling).
most important things that i've noticed from watching kids and taking faceoffs here and there is the importance of scooping up the GB after you've 'won' the faceoff. FYI - you havent won the faceoff until you have gained possesion of the ball...

you could also search Alex Smith on google - probably one of the best Fo/Go's in the world right know.
also another good resource.

there have been a handful of very good, very consistent FO/GO's that i've seen play in wisconsin over the past year or two, but they're nothing in comparison to the guys from chicago or michigan or ohio... getting to be proficient at the faceoff x is a matter of practicing your moves thousands of times a day,,, literally thousands, that's what my friend had to do when he tried taking faceoffs for his high school out east.
i could rant on, but i have to leave for work... try this stuff out, see how you like it.
