12.5 degrees is correct for the initial E/O pitch target. The best method is to hold that pitch until the SRS bar stabilizes and then follow its' pitch cues. BTW, there was a comment from someone about use of FLEX when you're heavy. If you are using FLEX, the performance calculation is predicated on maintaining the reduced thrust value throughout the single engine climb, so you don't have to go to TOGA. That said, if you are heavy, using TOGA will certainly add to your comfort level. Just be careful about quickly shoving the thrust levers up to TOGA, as it will add significantly to the amount of rudder required. Be ready for it with your heavy foot.
WRT to NPAs, is your company using the fully managed function for non-precision approaches?
