Ripping Chain side plate angle.

[Walnut33]

I'm having some questions on sharpening some chains. Does everybody here sharpen their ripping chains 90* to the bar (side plate angle)? I noticed that the woodland pro chains (through Baileys) suggest a 80* side plate angle. This is for the 43RP (full comp.) which is a .404 pitch chain I use for my 880 Mag. I tried this angle conbined with the 10* top plate angle and it seems to take more of the front of the tooth than the back. I half expected this due to the change in the side plate angle. On my other saw (MS 390) I always sharpened my rip chians 90* to the bar with a 10* top plate. It seemed to work fine. Just wondering if i should be doing the same for these bigger 43RP's. Thanks to all.

It pretty much depends on how smooth you want the cut. 90 is gonna make more powder and cut slower, 80 is a little rougher but cuts faster.
