No secret with this unit.. this one just fits my head the right way.. When the system fits your head right the ripple issue is a lot less of a problem.. but i know what you mean about ripples.. The last piece i got from toplace had that issue with ripples in the front.. I think the alcohol slide might be a good way to get around that.. Spray the tape or glue/ or scalp with alcohol than attach and make sure u smooth out the lace or any ripples from it.. Thats the only way i can see..
