If you are trying to hide the fact you are wearing from another wearer then its true tape is slightly bulky to a some one who is looking for it.

I use ST-30 all around and walker no-shine in the front. I change the front every three days and remove the system about once a week. The walker no-shine is pretty thin and i think its pretty undetectable to an average person. I mean if some one is going to sit there and with a magnifying glass they will notice something is a little off no matter what.

What I always say is try both and see what works for you. I think tape works fine, I have 63% density in the front, I could see if you had less density it becoming a problem. I also scallop the tape in the front, which also helps get rid of the appearance of a straight line. Others are more particular and like to use glue and don't like tape all the ways to the front. Try both so you make your own choice. Tape to me is just so easy to apply and remove I couldn't be happier with it.
