Your 032 could pull a 20-inch bar but it will do so at a far slower rate than a 361. I am sure your 2145 could cut hardwood with a 20-inch bar but I will be done and back home with my 460 while you are still working.
There's a right tool for everything, and too many of you here are offering less than the best advice for the OP. He doesn't need the power of a larger saw. Maybe you should re-read what his intended use for it is. The MS 250 is more than enough for what he needs. As for the "rule"- never heard that one before. Not from any of the loggers I have known, or any of the saw shops I frequent, so I call BS on that, especially if the saw is set up right, and has the proper chain that is sharpened correctly. I don't have a 20" on my 2145. I have the 18" you said required at least 60cc's, and it clearly doesn't. Is more power better? Sometimes, but is it needed for an 18" bar? No.
BTW- I'll put my 2165 against your 361 any day, on any wood, or my 2186 against your 460 and be home before you have even gotten back in your truck.
