Back in the old days (late 1990's through 2005), I used to get a thin poly perimeter on the sides and back (never the front). Some around here used to call it a PSB perimeter. I did love the ease of application, but I had a problem with my 65% density showing a difference in appearance between the thinskin and lace areas. It was very obvious in thinner spots. I am thinking that you are having such success (Cowboy) because of your higher density. At age 44, I don't want to increase my density any more. If anything, I want to lower it soon. So I think I may have to keep all lace. I am still curious to see a photo of the underside, so I can make sure it looks like what I used to get.
