Awesome guys, I can't wait to see these fly this weekend!

BW, how much weight do you need to loose?

Are those dowel standoffs holding your rear motor support? If so how much do they weigh?

What RX battery are you running? I'm running a TP900 mah LiPo that weighs very little (can't recall right now exactly how much, I think like 32 grams). Also, are you using a switch on your RX battery? If so you can remove it and just plug in servo extensions each time. I've heard that the aileron servo extensions on the electrics don't need to be 22 ga as there's not so much vibration, 24 ga would save you a few grams. If you're using a throttle servo extension it definitely doesn't need to be 22 ga.

Another big place to save weight is in the wiring of the controller. Are you using 3 deans connectors or just two?

I really don't think the TP 4200's will be enough if you're trying to keep the discharge rate below 80% of the battery capacity, especially in the wind.
