I didn't mention it in my previous post, but after a couple of other have mentioned it, I'll vote for the 400. If you don't mind the price over the 362, the 400 is better in every conceivable way.
Although Stihl says the 362 is lighter, I'm convinced that the 400 is the same way...the 400's built on the same chassis and has a lighter rotating assembly, so it shouldn't be any heavier. I own a 400 and it doesn't feel any different than a 362 when you pick it up.
Where the 400 doesn't feel like a 362, is the power. The 400 blows the 362 out of the water...it's a strong little saw. I own a wrap handle 400...it was pretty good stock, but I did some machine and port work to it...it continues to impress me with it's power/weight ratio compared to other saws. The 400 has the balls to run a longer bar than a 25", my ported saw easily pulls a 32"...it's just that the oiler was tapped out at 28". It's the same oiler as the 362, and there is a workaround for both saws to improve oiler performance. I ended up with the 461R pump and control bolt in the 400 oil pump housing.
