That looks interesting. Does that set up annoy you when doing shoulder checks? It looks like it would limit you field of vision.
It removes a tiny tiny piece of peripheral vision, but I haven't noticed it being an issue. I guess I could put it on the left arm.

Didn't get me off but threatened twice too, ending with the third one by nudging my rear wheel at 10mph. Someone got his details (didn't think to get his at the time) but it would be my word against his and he had a passenger who would no doubt give a statement in his favour.
