Gripped Camera Bag Suggestions

Gday all,

Just wondering if I can get some idea's / suggestions from people regarding a bag for the following gear.

Gripped Canon 50D with Tamron 17-50mm attached (approx 1.5 time nifty fifty length)
430EXII Flash
50mm f/1.8
Cokin P Series kit with 3x filters
Other small things like shutter release etc.

I did have it all in a Lowpro Slingshot 100AW but have grown out of that since buying the grip this weekend.

I was considering a Kata 3n1-20, has anyone got a gripped camera in one of these?

I'm looking for a backpack style bag.

Any other suggestions greatly appreaciated

that'll all fit fine in a 3N1-20.

if you plan on getting more gear in the future, a 3N1-30 might be better.

I use a Lowepro 250 with my gripped 7D. I usually have a 17-55 plus hood or one of my tele-zooms attached.
