In general, I hate redistribution. It might seem innocent when first implemented but it can bite you in the ass later.

My stance is to never use it unless you have no other choice.Even then tie a route-map to it ALWAYS!

So in large environments you'd have a really long BGP config utilizing network statements?

I guess "never" was the wrong way to phrase this. When I wrote this Im pretty sure I was talking about all redistribution in general not just IGP->BGP. Also think I just came off a mean INE redistribution lab...

In "most" standard BGP situations I would lean towards network statement or aggregate addresses to keep the BGP config simple. But in a situation with a large number of prefixes that cant be aggregated then sure it will be cleaner to place them all under a route-map/prefix-list and redistribute. MPLS VPN sure redistribute all the time.

But just like always I think it depends on your situation and what functionality you want. Redistribution allows you to dynamically add/remove prefixes via your IGP  where-as with network statements its back to a manual process unless your subnets fit within an aggregate.

Gotcha - thanks for the tips.
