Well I moved the battery to under the tank and it did not help much. Guess the lead it will have to be. I didn't relize it would be such a debate. I can see how a heavier plane will feel more stable , but less agile. Guess it will be the happy medium. The plane will still be under 7 lbs. Plus it's my first build, so if it flies 10', I'll be happy as can be. Thanks all for the replies.

Oh ya by the way, good idea w/ firewall battery mount. Just not enough room in the sse.
