I have a Benchdogs router table extension on my saw, but didn't know they made anything like parallel guides.
By thin stock, are you referring to narrow cuts? I have both the Woodpeck and Festool guides and use them both for narrow cuts. Whichever gives me the most board under the track is the one I use.
Half of what we read or hear about finishing is right. We just don’t know which half! — Bob Flexner
