Hey Lew - have you ever used an 8" machine?

Actually, I use a 9" right angle machine equipped /w/ 16 grit disks as my
basic fiberglass sanding tool.

Trust me, it can be a bear some days.

If you have, ignore the rest of
what I have to say, but if you haven't then let me say that you won't want
to replace a 6" tool with an 8" tool. (intentionally leaving that wide
open...).

Naw, naw, won't ignore you.

I'd go with both in my inventory if I were you. 8" is great for
knocking down big stuff and for overall leveling, but it won't get in
where
6" will and it gets unwieldy after a while.

That's why Fein makes a detail sander, IMHO.

Far more useful than any ROS , IMHO.
