The thin walker tape hasnt held up, it turned to a goppy goo on the third day and even started coming off the lace leaving a greyish line below and a little ways back from the lacefront, the heavier walker tape behind and around the sides has held up beautifully except i dont think it will make a perfect hairline. I have decided to just use the walker heavy tape around the entire perimeter and ive gotten my hair cut like the guy in this pic, it completely hides the hairline and looks quite stylish so im happy for now
Also to give you guys an idea of what the tapes up against, i do heavy lifting (3+hours) every other day and on the days in between i do two hours heavy cardio, so most of you probably would be fine with the thinner tape for long term hold
