I like the 1st 550 OE over the newer. They weighed same as NE 346 and felt great in the hands.
I ran some 550 MKII and they lost all that trying to make them better. In case 12lbs PHO now. But they do run great if you want heavy 50cc.
550 OE out cut NE 346 and OE 545 cut even with the NE 346.
Ported MKII 550 and ported 394 n pic I got to check out.
Why we can choose any saw we want without some bonehead in this thread trying to belittle folks for their choices of a chainsaw.
They cut wood and thats all.
PHO OE 550.
