Need help to choose bag

I have the following:

7D
28-135
70-200 2.8 L
150-500 Sigma
filters
flash
some misc

Will a Lowepro Slingshot 300 AW hold the above?

Other suggestions? Thanks in advance.

Can anyone help me choose a bag?

Backpack, shoulder bag, messenger bag, or sling bag? Those are 2 good sized zooms. Not sure if they'd fit in the 300 or not. A good place to check bags is Cambags.com. They have lots of user reviews with pictures. Do you already have a bag?

I have a 7D with grip, 100/400, 70/200 2.8, 17,40 85 1.8, 50 1.8, 430exII, plus some extras in this bag. It is a very nice backpack. check it out.

I have 5 bags, different ones for different applications. 95% of the time I use my TENBA Messenger. I LOVE IT. It can hold my 70-200, 24-105,Flash, 50mm,and more plus accessories, Laptop if needed. It has a removable insert so the bag can be used for other purposes. The padding is awesome. Now My equipment comes with me anywhere.
