I've managed to put 6 tanks of mix through the 355t this weekend, and it is above and beyond what I was expecting from the spec sheet. It revs fast, its comfortable in the hand, the exhaust note is awesome, and it has as much if not more power than a cs-400. I cut everything from white oak to alder, nothing bigger than 10" diameter and was impressed with each cut. The factory carb setings are spot on as well, it four strokes with no load and is very crisp in the cut. I'm going to put a tach to it on Tuesday when I go back to work just to see what it spools up to. If I needed a top handle saw, this would be it.
And I was running it on Red Armor Shindaiwa oil, no smoke or smell whatsoever.
