Tokina 11-16 on D600

Good morning all....  I'm about ready to jump on the FX bandwagon, coming from a D7000 and a variety of DX and FX lenses.  I have the 35-70 f2.8, 70-300 VR and 80-400 VR FX lenses, so can shoot from 35-400 with my current kit.  I'll sell my DX lenses 35 1.8G, 17-50 f2.8 Tamron, 18-105 VR and 40mm f2.8 Micro, but am unsure what to do with my Tokina 11-16 f2.8.  I really like this lens as it is fast and sharp on DX, and have read that it is usable at 16mm on FX without too much vignetting.

Can someone that has the 11-16 and a D600 please post some samples at various focal lengths and apertures.  Any thoughts from the forum on keeping the lens?  I'd like to get a wide angle FX lens, but am unsure what to get.   Any suggestions are greatly appreciated!

Cheers,
D. Hamments
