Oregon file guide

That looks like a good buy.
I would use something like that at home but I prefer the roller guide when working in the bush.

What type of chain do you use and how do you grind your chain for milling?
I always like to hear what other people find works for them.

I was looking at the Oregon file guide, the one that clamps to the bar and the file is mounted in it. It looks like a pretty good machine, has any of you used one of these or something similar? Wondering how well they work and are they easy to use or awkward
I have a 3120xp with 37" bar for milling and need a good chain sharpening method. Any feedback would be great.
