OK this thread hasn't been much help. 
Sounds like bottom line is both are fantastic options. I think I'll probably end up with the 135, I feel like it'll get more use due to its compact size, and plus with the current rebates a sub-$1000 price tag is a lot easier to swallow than $2k+ for the 70-200. Thanks for everyone's opinion, at least I know I can't go wrong either way.
