People find tape perfect for the back and sides (and some, even for the front) but I've never got on with tape.
My skin is too oily.
Its a shame because the clean up is far easier with tape than with glue.

My units are full Swiss Lace and I use just glue, all over.
I've tried every sort of glue and the only one that works for me is ORWG, which stands for Oil Resistant White Glue.
I find I can get away with 10 days attachment with maybe a couple of frontal retouches, in between.
Most people believe glue is best for lace because the lace needs to sink in to the glue to fully disappear.

I hope this helps.
