My last years firewood oak log pile, "butt" diameter up to 1.4 meters (~55"):
All I had at that time where 20" B&C setups for both my Dolmar PS-6400 & Dolmar PS-7900.
It took two sided bucking on the large diameter logs, but neither my Dolmar PS-6400 nor my Dolmar PS-7900 missed a beat bucking them with the bar FULLY buried in oak.
Until this year I used exclusively Dolmar branded Oregon loops and occasionally Oregon loops.
All I ever used is round filed chisel full complement 3/8" .058" and it served me very well thus far.
The Dolmar PS-7900 is more fun to play with hands down, but the Dolmar PS-6400 sports a up to 50% better fuel economy.
I love them both, each for their own pros!
