Hi Matthew,
Glad to hear about your positive experience in starting out wearing hair. We have a thinner all poly unit called the New Generation base (TL 700). It's much thinner and has an excellent hair line---as good as a SFS lace unit. Just a suggestion in case you want to try another all poly unit. As for the tape and glue holding to the lace unit, sounds like the bottom of the base needs to be cleaned so that any residue is removed and you get clean lace to adhere to. Just take a soft cloth and dip it in either alcohol, Lace Release, or even the suds from Dawn dishwashing soap and swab the bottom of the base on the lace unit. This will remove residue and give you a strong bond.
Regards,
John
