How to work with 30p and 60i on same timeline?

I'm shooting a concert in a few days with 3 cameras. 2 of them will shoot at 30p and/or 60i. The 3rd will only shoot at 60i. The final renders will be MP4 for web and computer viewing. I've heard (and this may be wrong) that 30p would be preferred for shooting. Is there much, if any problem shooting on 2 cams at 30p and the other at 60i? What should the project settings be? Or should I shoot with all of them at 60i?

Thanks
