I have a 455 Chris and it's a good saw albeit a bit on the heavy side. I cut with a friends 359 a couple times compared to my 455 and the difference wasn't that huge performance wise. However there is a night and day difference between the 455 and the 372XP. The 372XP has almost the same weight as my 455 but it's a TON more powerful. I cut a 24" log last night on a friends property and the saw didn't drag a bit. Very happy with the saw so far. Steel dogs are very useful when felling trees. Those stay where they are.
