If you are using semi-chisel/half-chisel chain, however it is worded, you'll love using full-chisel chain on the 036PRO. Full-chisel is the way to go for fast cutting on this saw.
Personally I love the balance of the 20" bar on this saw for most firewood cutting. Full-chisel may wear faster, but if you keep the saw out of the dirt you should not notice much of a wear difference in the cutters.
