How to resolve disagreement with project teammates over which professor to work with? I would like some advice about a conflict I am having in a graduate course taught by two professors. I am pursuing a masters (MS) degree in Finance and for the capstone course in the program, each group (3-4) students is required to complete an individual research project.

The professors responsible for the course both have PhDs in Finance but in slightly different research areas. My team-mates both insist that we only work with the professor who is more specialized/knowledgeable in our area.

As the course is taught by both professors  equally, I feel it is important to keep both professors abreast of our progress. I feel fairly confident that both have equal weight in evaluating us and I don't want to slight either. How should I explain this fact to my team members as I am the leader of our team? 

For additional background, my team members are all from China whose academic culture is wholly different from Western standards.
To expand the comments above into an answer: ask the professors what they think is a good idea, ideally both at the same time (e.g., at the end of a class where they are both there).  You have less chance of coming off as disrespectful, since you approach from the perspective of a student desiring guidance.  If they say you should work with both, then that's probably a fine plan to follow as well.
