What you say is true but actually from what I've seen on a birding forum, at 500mm the Tamron is sharper than the Bigma. It's also a bit smaller and lighter.
The Tamron is 200-500, yes, but my intention was to get a 70-200 f/4 L later on anyway so that actually works out quite nicely. My ultimate goal (as far as lenses go) is to use a 70-200 L, then 300mm L prime with TC's for birds, etc. After that I'll be pretty content.
A 100-400 L would be nice, I'd take one in a minute, but I think in the long run I'll be happier with the 70-200 L and the 300mm L prime with the 1.4 TC. That will cover my needs. I don't shoot indoors or sports or things like that so use for those purposes is not a major concern of mine.
The Tamron is the best choice for me for right now since things are a bit tight right now.

Sounds like you have everything under control man ... then go for it. As for the sharpness I would check out the MTF charts at photozone.de and compare the two lenses by objective lab testing.
