I have owned both the 361 and the 5100 at the same time (Sorry, no timed cuts...just opinion). IMO the 361 had a small edge with 20" bars, in full bar cuts. But... 18" bars or less and its a pretty good match. The 5100 hundred is a tenacious little speed demon. Both good saws, but I sold the 361 and now own 2 5100's. I just can't help but think that a 59cc dolmar motor on the 5100 chassis would stand above the 361 and 357, at any comparable bar size.
Oh no! ......... and probably not worth a 35% increase in price to power, over a 5100......
Sounds like Scooter is ready to rumble!:jawdrop:
