I think one of the reasons you are getting the "stay away" is that the Kamasori was designed for Monk A to shave the head of Monk B. It was not originally intended for Monk A to shave Monk A with it.
It has a front and a back, is made to be held with the dominate/design hand. When you shave "western" you can (and most say should) learn to shave with both your dominate and "weak" hand so that you can get be best possible approach. WTG, XTG and ATG normally requires shifting the grip and hand as you move around your face.
If you are using a Kamasori to shave someone else this is not a problem. When you shave yourself you are going to have to make compromises...lots of them.
Either hold the blade "backwards" (face in) and/or limit the direction of the pass and your ability to see what you are doing.
Want the style of a Kamasori but the directional flexibility of a western? Give a Feather type razor a look.
In the end you get to do what you want to do, like someone said in another post about the subject "it's your face and your razor, you do whatever you want".
I do know that the info I received on SRP saved me money, time and blood...and made learning how to use a Straight a great experience.
Good luck!
