I fly primarily heavy piston and light turbine twins. Given sufficient runway, i always opt for blueline prior to a posiive rotation. In piston planes such as 400 series Cessnas that will accommodate strut variances to allow for a nose down runway attitude requiring a positive rotation, I’ll do that, stick to a Blueline rotation and, if I’m after balanced field length, know that I can make it off even without a published V2.
