slightly increase the angle
here is what worked for me:
1-do it SATURDAY Morning (you dont wanna try this monday morning, get a nick, and go to work looking like a freshly made Frankenstein)
2-make sure you razor is in perfect/good shape, using whatever method you like (yes, the "good shape" do the trick for me...I acctually "measure" the sharpness of my razors based on the XTG performance)
3-prepare you skin :soapbox:
4-start with your regular WTG , stretching the skin and gradually increase the angle (5 degrees each stroke) until you reach the XTG stroke
*very important, the skin stretch in my case if different based on the type of stroke. I.e. when I go WTG I bring my skin up (toward the sky [haha]). for the XTG i go sidewise. ATG...well..I still need to master this one.
take care and enjoy your BBS (at least for a couple of hours)
