Most interesting information during T/O for me is windspeed, especially in an ATC-Environment where you ask: 'What's the wind?' and they reply 'What do you need?' And the Head/Tail-Wind-Component is correct, whereas the direction becomes only when approaching liftoff.
If you're using reduced Thrust an calculated with L/V-Wind and then you see 10 knots or more from behind, maybe it's a good idea to go up to TOGA Thrust.
