I am thinking about chopping it flush back, but the 2 side locating screws wont fit, and i dont want to lose any rigidity in the front of the guard.

As for the trip into the bushes, had a rear wheel puncture going through some twisties, didn't realise until I leant it over for a right hander and the back started to slide. Choices were Hard black stuff or green stuff. Green was better.
