How can i explain this better.... (please note that my car is getting better reaction wise and i aint just arguing for myself)Pro tree for me, hate the sportsman tree and there really is no advantage one way or the other. If your car reacts slow, it'll react slow to any tree. As Mark says, the green light is the green light.
If your car is slow to react then a sportsman tree gives you the opportunity to 'go' earlier. For example you can hit the throttle on the second amber and by the time your car has decided to start rolling the green is there. On a pro tree you will always be a few tenths after the red light.
As for you Andy... Just put something on your visor so you cant see the first 2 ambers You are going to win the race anyway. At east let the opposition experience the effect of you coming passed at full chat. Always enjoyable :tup:
