China Eastern Airline's baggage policy experience... Anyone?

I've a flight on China Eastern from Shanghai to Delhi in economy. For cabin bag weight/peice limit, I did some searching around, and found from http://www2.flychinaeastern.us/ctva781/tripPrepara... the following: "Economy Class - 7kg (15 lbs)"

Now my question is to those who had flying experience on this airline:

Are they too strict on baggage? I've one roller bag with my laptop, that should fit under 7 kgs. But I've another cabin bag for both my SLR camera and lens, and a camcorder.

These items cannot be kept in my checked bag due to obvious safety issue. Also their website doesn't says if they allow other bags like camera bags, etc.

When I called their office in US, the agent was very impatient to hangup on me & barely told that the cabin weight limit is only 4.9 kgs. So I'm confused.

Do you think I'll be able to carry my rolling laptop bag and another camera bag (as described above) without being forced to either check in one of the item or pay excess baggage?
