If the 16-35 is as sharp as the 14-24 I will certainly sell the 14-24.
The 2 mm extra is handy,however to be able to use filters is a bonus for me.
Also,14 mm is very wide anyway,16 mm is already very wide.
Being F4 makes it a bit lighter as well and should be still easy to focus.
The VRII I could live without.
