Had an old CTmidi c.2010 with the small hose. Latest CTmidi purchased had I believe the 36mm, but maybe it was 32mm. Way better flow performance and less clogging esp. When vacuuming up things other than sawdust. I would not consider the smaller diameter hose for longer lengths or shorter lengths either one? if I was spending the money on replacements, but I'm not sure what other factors make 27mm desirable.
Thanks for the feedback on the 5m hose, I'll give it a closer look.?
I do have a Mirka Deros sander, the 6" pad, 2.5mm orbit configuration. I really like it, particularly for fine sanding between paint or finish coats. I don't notice the paddle switch, at least in a negative way. In my experience it's very intuitive, and I'm not sure I'd go back to a sander with a On/Off switch. Happy to discuss further if you'd like.?
I also have the standard configuration LEROS sander, and have noticed that Mirka recently released a shortened version that would seem well suited to tables and other panel goods....?
