Personally I shoot Canon, that being said I think you should go with Nikon. #1 reason is you can borrow Vic's lenses. lets say you guys are shooting the same event, someone can use the long lens and someone could use the fish eye If someone forgets something there might be a chance your equipment would integrate. There is a chance your battery packs might interchange (do the homework), this could come in real handy if someone forgets to charge there shit LOL. You see where I am going with this, it will give you some options as a team to make it happen.
