I ran an 032 Stihl (51cc) for 20 years with a 20" bar, and it was never lacking power either. An MS 250 is alll the OP needs for his intended use if he is wanting to stay with Stihl.
This is not a 'line' it is an age-old rule-of-thumb to size a chainsaw engine to a bar length. I put myself through college by working in a variety of lumber companies and have been running chainsaws for decades as well. 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.
