I'm left foot forward, and usually take fast corners with pedals level rather than outside down and knee out. I have tried putting the right foot forward and it was OK, but I'm more comfortable left forward.

IMO, there's no benefit from from putting the outside foot down instead of level or hanging out a knee for either clearance or dynamics (or specious CG rationales). I used to race motorcycles, which of course had no option of putting the pegs anywhere than where they were, and where hanging out knee could be of value.
