no 12guns, thats not what I'm saying. I meant that while I don't think there's a better saw made than the 460, I don't think you'll be able to tell much difference between the 440 and the 460 for your application. The 460 really shines with a muffler mod, whereas the 440 has a pretty open muffler in stock form.
Just don't think you'd really notice the power difference as much as you'd notice the weight, and price.
The 440 would be a screamer in your firewood, and you'd keep some hard earned cash in your pocket over the 460.
A 440 running an 18-20" B&C, with an 8 pin sprocket, running 3/8 full skip would be all you ever dreamed of in your application.
You wouldn't be out cutting all day, you'd be done quicker, with less fatigue verses a smaller or larger saw, and your smile wouldn't wash off.
