messenger bag suggestions

[JustinL]

I'm looking for a messenger style bag with fast lens changes in mind. I would love to go with a Lowepro belt set up but have a budget of around $200 for now. My needs would be for it to be big enough to hold a 5dmkiii with 70-200 attached along with a 24-70 and 16-35, and maybe one prime like a 50 or 85 when the camera and mounted lens are on my neck. I wanted to know if anyone had a bag they love that can handle those needs. so far the best thing I've come across is the Think Tank Speed Racer but I think it might be a little small.


Thanks
