John - Thanks for the rapid response. I believe my next order will be for a unit with iLace. A couple more questions:

1. Is the TL iLace unit the same as what is called a "silk top" hair system?

2. Besides the SFS perimeter, is it possible to design-in 3-4 small (1-2 inch) pieces of polyurethane for attachment of tape or adhesives? I was thinking of adding a strip in front, 2 on the sides and one on top/back. The strips would be underneath the iLace so as to be invisible.
