Bags are a lot like clothes... Everyone likes something different, and what one person likes another person hates.
That said, I am a cheapskate and I have never bought a new bag. Part of that is because I don't know if I will like it or keep it. eBay, Craigslist, and buy/sell are my sources.
I have two sizes of the tamrac velocity and I really like it, but I think that would be a bit small and things would not fit wellfor what you want to carry.
I keep all my equipment in a big pelican, and I have about 6 different bags I will use depending on what I want to take and what type of shooting I will be doing. Indoor sports is usually one body and lens in a simple shoulder bag. I dump the bag under a table or leave it in my car and go with a blackrapid style strap. If I am doing a photo walk type of shooting, the velocity bags can carry quite a bit and be easily accessed without setting the bag down. If I am shooting t&i, I have a tamrac backpack that will hold all kinds of redundant stuff like extra body, extra remotes, another lens, batteries, iPad, etc.
So in summary, it really depends...
