having been a recent 3-4 months convert to DE shaving, (mach 3 before) I found the transition of technique not a big issue, within 4 shaves I had a BBS, used feathers successfully, on the 3rd week (15-20 shaves) with only minor 2-3 weepers, and never had any issues with my neck . . cettainy not the issues around irritation and rough shaves . . .
it finally dawned on me this morning, I have no adams apple !!!!
i have a fairly thick neck (not fat ) and the surface is uniform with no bumps or change in contours, i can do an under chin ear to ear sweep, in one motion with all my razors, and all my blades, I usually do 1 WTG, then 2 ATG ( 1 from each side) passes and I have a BBS . . . all due to a thick, but unifrom neck area . . .
