Being familiar with New England winters and summers, either 13 or 16 will do you just fine. Depends on which one you like the feel of better. I've got a 13 that holds its shape well and is more than substantial enough to hold up to a NE winter. But it's also not so heavy that it's unbearable in the humidity and heat of the summer. Do some comparison. The folks here are a wealth of knowledge, but when it comes right down to it...pick what you feel comfortable in.

Oh yeah....welcome to the addiction!
