I used DE for about 10 years exclusively (on my face) but eventually started keeping some form of a beard most of the year. I shave my head with a cart (Fusion ProGlide/Mach3) as a DE is too much work on my head. I loved the DE experience on my face and got great shaves with little more time than carts.
You and I are cut from the same cloth. Cart shaving on my head is just quick and easy and allows me to devote due care and attention to a wonderful DE or SE shave.
