Stihl USG grinder  I went with A +40 /+40  B +10/-10   C +30/-30   they show to use 15 on B but I like 10.

Better give you this link for those that dont know the USG  http://www.stihlusa.com/WebContent/CMSFileLibrary/instructionmanuals/USG_sawchainangles_chart.pdf

Semi chisel chains do not normally have the top of the cutter drooping 10 degrees.

But most chisel chains do. You can see it if you look at the cutter head on.

Chisel chains have a a sharp corner where the vertical and horizontal parts of the cutter meet. (like Stihl RS or Oregon LG)

Stihl RM is a semi chisel cutter and is always flat zero across the top cutter and are rounded off between the vertical and horizontal parts.

Semi chisel chains are better for dead and dirty woods.

Pretty sure I have posted these before.  Current Oregon recommendations show 30/55/10 on a lot of chains, that they used to say 30/60/0. These things change. I would not get hung up on it - pick something that works for you.
