Match HVX200 with EX3, any advice?

On a very short notice I am about to be sent some footage shot on HVX200 and on EX3 that I´ll have to match.

Since I don´t have yet the material to work on, I wonder if anyone has had any experience on that matching and could give me some advice and tips.

1. What are the clues to look into?
2. Would it be better to use the HVX shots as the base and match the EX3 to it?
3. I believe the EX3 will be sharper, what about contrast and color bias?

Any suggestion and advice is very wellcome.
Thanks in advance.
