I like blue for touch ups, grey for converting round to square and the salmon one gets a fair amount of use. Mine has a multipoint dresser for the top plate and a single point for the side. I should pick up a spare or 2 just because. If you're open to trying new things, look at the progressive depth plates. It's a more precise way of maintaining those. Each individual raker is tuned for the length of each cutter. The Husky roller guides have them built in. Just lay it on top and file smooth. And WCS has a nice one but the metal is a little thinner. Main thing is it has way more options of how thick of a chip you want to cut with. This really lets you fine tune the chain for your preference in chain "bite". Use a progressive depth plate? Check this one out 24" full comp should be cutting quicker than skip all day. Even beyond that unless you're getting chips clogging in the kerf (on softwoods) with it.
