I have bucked ash last Saturday, I utilized a raker modded Oregon Vanguard chain sharpened with a Archer Fast Filer jig - the chips were up to 1" long while bucking straight grain, they got significantly longer going through knots.
The loop is a little on the aggressive side.
I think the wood species matters a lot.
Bucking Turkey oak generates small chips that break apart, bucking beech will make fingernail sized chips, this ash I am bucking makes noodle like chips - all with the same chain and saw.
