The 462 smokes a 361 and 362 all day long, especially in bigger wood. I cut side by side with both saws regularly (buddy owns a 361 and 362). The bigger the wood, the bigger the difference, and it ain't "buyers remorse". A 462 trades wins with a 500i, not a 361. Also, the 462 doesn't have any "vibe" issues. Some of the stuff I read on this site is baffling.
My experience sings the same tune. I run an MS 261 and MS 462... ran an 029 Super with an 044 Magnum in the past. The 261 is great for small stuff... excellent power to weight ratio, less fuel consumption, and that smooth .325 pitch. My 462 comes out for big stuff and has excellent power to weight ratio as well, and has the power to pull up to a 32" bar in Doug Fir if I really want it to.
The 462 with 28" bar, skip tooth chain smokes every 361/362 I've cut next to as well when it comes to larger wood, especially older wood. Go buck a <100 year tree vs >400 year tree, both the same diam and you'll see the 462 outshine. Cutting small, young diam trees doesn't show a meaningfull difference in one cc class compared to another, ie. my 261 is close enough to my 462 in <12 inch wood, so I use the much lighter saw.
I've always looked at the 361/362 class of saws almost as an attempt for a "Goldylocks" saw, but falling short in power with bigger, older wood or in power to weight ratio in cutting small stuff when a smaller cc saw is all that is needed. I suppose the MS 400 could reign as a better "Goldylocks"... I've always wished for more power, not for a handful of ounces lighter. If I'm not mistaken, the 400 was aimed more for smokejumpers?
Three key things I've found that matters on any cc class of saw... chain filing, bar maintenance, and tuning in the wood, not on the bench. I've bucked a cord of 24" wood just for fun in no time with my 261... curious if the original poster has all three things aligned, making sure their 361 is in tip top shape. It should run a 24" bar no prob with a sharp chain, dressed bar, and proper tuning.
I'd suggest a 461 or 462 all the way for the original poster. If the 361 is in great condition, sell for more cash rather than trade for $300 if finances permit and work on getting a 261. I've found a 50cc saw with a 70cc compliments each other very well in alot of work... if big wood was the norm, than my smallest saw would be a 461 / 462, maybe that new 400 once proven. Otherwise, if they keep the 361, I'd look into a 500i.
Looks like post started back in April, but if they haven't pulled the trigger yet, hopefully more feedback from experience helps...
