Rainboe, good post again! Agree totally!
Also I say that if you are going to make any mistakes apply a bit too MUCH into wind aileron rather than not enough. The effect of spoiler deflection on lift is, I agree, quite negligible and is of much lower priority than just keeping the wings level during rotate.
I suppose I am quite sensitive about this having started on the B 707 where if you did not get it right you would end up scraping a pod! (Also applied to the landing).
All we are talking about is normal crosswind take off technique for virtually any a/c - back to basics!
