I have a 2520 with a 64" puma. Great combo in everything except wet snow. I've logged over 10 hours so far this year on the blower in every type of snow. 8-10" of powder is not a problem unless I get impatient and try to go too fast in HI-range. Wet snow requires patience if you need to throw it any distance. Thankfully the hydrostat makes it easier to control the feed rate.
The main advantage for me is that light snow falls are cleaned up faster with the 64" over a 54", and manouverability is better since the front tires won't cut into the unblown snow unless turning very sharp.
