I have used the jigs, now just hand file. Don't let the perfectionists BS you, if you keep your depth gauges even and set right, a saw can cut very good with wonky looking teeth. I am very serious about my saws, but if you angle varies a little it won't be noticable.
On another note, keep an eye on burrs that can form on the edge of the bar. The best cutting chain won't cut if those burrs hang up on the wood. If you are getting a lot of those burrs, you are ruining your bar, sharpen better/more often.
