Ya, field helmets are actually really good as goalie helmets. A lot of box goalies use them. Never really liked them my self.
And if you get a chance (or get bored) you should really just try lacrosse out some more, get used to the stick because it's really pretty fun, even just playing wall ball, which is much harder to do with a puck.
I do watch UFC occasionally (although I'm the one who always does them at work, so i don't see much

) although I'm not as into it as some people. Just follow it enough to know what's going on.
