I love my 372, but if I were buying today and planning on using/burying more than a 24" bar routinely, I'd opt for the 576. They are very smooth, but balance better with a 28"+ bar (especially in 0.063) and have noticeably more torque. Of course there's still a ported 390xp in my future (and I know it's not an option for you) which would also dissuade me from owning one. I know that the 372 has been a fallers saw for a long time, but cutting mostly Hedge, sometimes large, my ported 372 is nasty in 24" wood, but after that I like the bigger boys.
