I recently bought a used 066 off CL for $400. I didnt have any wood big enough to challenge this saw so I asked smokinJay if he had a log for me. He comes up with this 54" monster! No pics, he may have some. Anyway, the winner is......the 066! Holy chit does that thing run! Ive never ran anything larger than a 440. WHAT A DIFFERENCE! It made pretty short work of a monster log. Threw the chain on the 28 and boogered up the drive links so I had to finish with a 20".Luckily there wasnt much left. WOW! Just wow. You can bury the 20, lean as hard as you want, and the chips still fly! My 361 is gonna start getting dusty I think! Shelf dust that is.
