It won't all go...

I need a new bag. I've outgrown the trusty Lowepro Mini Trekker at last after many years service. Crammed in here is...

Nikon D90
Nikon D70
Holga 120CFN
Sigma 70-200mm f2.8
Sigma 28-300mm
Nikon 18-70mm
Nikon 50mm f1.8
Sigma 2x televonverter
Sigma 105m Macro
Various leads, filters etc etc

It weighs a ton and I want to add very soon a Tokina 11-16mm f2.8, Nikon 35mm f1.4 & a Nikon Speedlight SB900. Therefore need bigger or 2nd bag. Want a Nikon D3s too but that's not likely I suppose!
