Strika, whilst I agree with your thought process I think you are not articulating yourself well. As the only people who were there are Tym2go and his mate one can not accurately say what the situation was. The sticks did cause the crash as the rider had not learned to deal with such a situation, the flip side is not all are capable of this in any case. Some are capable of riding over sticks without fear others can not. The difference between the best and the worst is self belief and the panic syndrome. No offence Tym2go but what sets the better riders from the lesser ones is the ability to process information, the more you can process the more you can deal with. Panic is caused by the brain tensing the muscles as it can not deal with all of what it is being presented with. In your case riding at a fair speed (relative to your ability) through a corner was what it could handle, coming upon sticks on the road and not being able to deal with the situation caused a panic reaction which is the normal way a person's brain will react if it can't process the problem.
However you can train the brain to deal with panic situations by practicing these situations in a controlled environment where the chances of failure are slim, as you succeed you can make the situation harder and harder to the point you are riding over a tree (okay slight exaggeration) Problem here is the first experience here has resulted in a crash.The hardest thing is coming back from a crash as you are looking for the next tree branch, so rather than wait for that to happen go find them and ride over them, practice and overcome the fear that is now present within you.
On fixing the fairings, I wouldn't just in case you have a garage drop

. What I would do is keep an eye out for a cheap set and get them so that when you upgrade the bike you can sell it looking all shiny and new
