Just look at the pictures you've taken, and ask
yourself what percentage of them would look better
if the background or foreground was blurred little
bit more. That's about the percentage of your
photography where DC would be useful.

Yeah! The 105's worth every penny if a 105's what
you want -- but since you want an 85mm, I'd guess
that you probably don't really want a 105mm or
135mm DC.
If the 85mm focal length fits the way you work,
the longer focal length of the DC's might just
get in your way. That would more than offset the
advantages of DC.
Besides, if you haven't missed DC with your current
85mm, you probably won't miss it with the 85mm-D
either.
