Sling bag and 70-200

I usually keep my 20D with a short wideangle zoom mounted as a walkaround but would like to have my 70-200IS handy to quickly change lenses. Does anyone know if those Sling bags have enough room to carry the 70-200IS and a 20D with short zoom attached?

The Adorama Slinger will.

I have the Tamrac Velocity 9 Sling Pack and it will hold a camera with the 70-200IS mounted (and the lens hood reversed).

I just got my Velocity 9 and it can fit the camera with the lens inside. The Slinger is slightly smaller, but could fit it as well.

Here is a thread with pictures of a 1DmkII with 24-70 2.8 and 70-200 2.8 IS in a Lowepro Slingshot 200.

I have the Domke J-803 and really like it. It might be a bit bigger then you want. I carry all the lenses and the flash plus some cleaning stuff in it (just). The advantage of it is if I put less in it reduces itself in bulk.
