But lets assume that I want to buy it without template and I need this tl700 base. I choose custom piece then, i get my head measurements in inches, but there are those A, aa, aaa contours, not every type of contours listed in "how to buy" guide. I wanted to know which on do I need to choose from those that are available, to have my hairline just slightly receded, like nw1,5 at most.
