I started out with the 22. Eventually got the boom arm and got tired of dismantling it and lugging it to the jobsite so ended up getting a Midi last year. One of the better Festool purchases I've made.
Now the 22 stays in the shop and the Midi stays in the van. If there are times that I know I'll be generating a lot of chips I bring the dust deputy, but usually just switch out bags. It's much easier on the Midi than the 22. I haven't had any issues with the reduced CFM and find myself switching to the 36 hose the same as I would on the 22, when planing or routing.
I like that vac so much I ordered another one, reconditioned.
