737-900 - which seats?

Hi

Doing an SEA-EWR R/T in a couple of months. I am pretty sure that I have a nearly zero chance of scoring a MVPG UG so I'm looking for seat suggestions. I am 6'2" so I usually go for legroom when I can which means row 6 and 17A & 17F . .

How are those on the -900? Are there seats I should stay away from?

Thanks
