You're only "confused" because you want to stir the pot. Try reading what I posted. Here, I'll bold it for you. It shouldn't be that confusing.
I'd even put a well tuned MM'd 039 with a good RSC chain against a 044/440 any day with same bar length.
I have a few for comparison and there really isn't enough difference to brag about. Fact. One built better/more durable? Up for debate in my book.
"....really isn't enough difference" clearly means one cuts faster than the other, or do you not understand that? You guys really should find something better to do than parse my words. If you believe, or have noticed a big difference in cutting, great. I haven't. 64cc vs 70cc.
I noticed neither of you commented on the $144 NEW OEM Stihl 044 piston / cylinder kit I just bought, as easily as I stated I could. Remember that little go'round? Several of you gave me a hard time on it 2 short weeks ago when I posted I regularly get them for less than the AM kits that were being hawked. I'm too old to be jerking peoples chains. I don't lie and don't exaggerate. I like to offer opinion and share experience. If you disagree with something I've presented, fine. No problem.
