I have skip and full comp for everything, except my 42" bar which has a loop of square skip and a loop of round skip.
Ive been cutting a lot of swamp maple lately, and have switched to skip, since those trees always seem to gush water when felling them, kinda amazes me how much they leak. Sappy stuff like pine i always run skip, and add a little trans fluid to bar oil - seems to help keep things cleaner for me, and helps bar oil flow during the winter, id rather have more oil on the bar/chain then just enough. Oak, Ash, other maple species, hickory i prefer full comp - sharpening takes a little longer, but honestly dont mind it, and can play with different angles etc
