Before I became a dedicated DE shaver, I used the headblade with good results. As good as can be expected with a cartridge anyway!
Once I got my DE technique down, I went straight for the head. The DE is one fine shaver for the ol' brain bucket!.
I found with an SS it usually took 3 passes and some touch up, but over all a great shave. I then had a brain storm and ordered a long handle Slant. WOW
What a difference!! 2 passes and your head will be slick as an Eeel!!! I have actually had folks come up to me and ask if I have my head shaved by a Barber...It really is that close a shave!
Personally, I like the chilly sensation of menthol while head shaving. Prorasso does a fine job, but if you want a bone chilling shave, you HAVE to order up some Tryphon Permafrost. Followed by a splash of Osage Rub and you will have a nice chilly head for about an hour! Great for summer shaves.
I have since tried a Str8 and a Rolls, but neither came close to the Slant.
Hope this helps. Feel free to ask me all the questions you want. I've been a headshaver for over 10 years.
