The Husqvarna 460 is a "landowner" saw listing at $500, the Stihl MS362 is a pro-level saw, listing at $770. You are not comparing apples to apples, even if the displacement (60cc) is the same.
The Stihl MS362 (59 cc, 4.7 HP, 12.3 lbs, $770 list) would be more comparable to a Husqvarna 562XP (60cc, 4.7 HP, 13.4 lbs, $750 list). Both are top notch saws, but are overkill for the occasional use that farmer2009 described (though if you don't mind spending the extra $ both are excellent saws and with proper care will last the typical landowner for MANY years). Both are spec'd to handle a 24" bar. However, these would not be my first choice if a was going to be doing lot of cutting with that size bar. They lack the power to drive it efficiently, and the balance is not good when wearing a bar of that length]
I understand your point, but having the Stihl 360 (about 4-5 years old) with a 24" bar, it is a bit front heavy, but with a sharp chain in seems to be efficient to me. I wouldn't even consider a 16" bar for this saw, IMO. Sounds like a Hemi in a golf cart to me. Now are there better suited saws? possibly. But I believe the OP stated it would be a one off situation, so I agree it probably is priced out of contention. I also have a Stihl 290 that would be a better choice in my mind, for the lesser pricepoint, but I am not familiar with the MS311 you mentioned, I only can go by what I have used. However the specs on the 311 sound good for what he is trying to do.
