since this thread i have owned a 661. while a decent saw it is way overrated by many already. ran a ported one done by a local shop and i was impressed with it's torque but i will still take a 390 or a 395. look at threads by the "great ones (some think they are anyways)". there recommendations on tuning is sometimes below factory spec lol. i tune my ported 390's to 14,200 and 661's can't touch them. not to mention 661's blow up. i heard the 390 should not even be in this comparison and that is kinda true not because of it's performance but because it is lesser cc's. the 661 is closer to a 395 in comparison and while i prefer the 661 for handling and weight it can't touch a 395 stock or ported. when it comes to AV husky have the springs down. so smooth yet don't feel like total mush. the 661 was an absolute failure by stihl. just handling the saw while not running you can hear the springs creak like they are stressed right out doing their job. mushy like a soggy noodle. i'm a cutter who just wants the best saw for me. i realize it is hugely dependant on preference but my opinion is that cookie cutters don't have a solid opinion. they base it on what the saw feels like in a couple cuts and not a full day of work. also a little bit of what their daddy taught them lol. anybody who tests a 90cc saw with a 24" bar is automatically not gonna be taken seriously by me and many others anyways.
