i currently wear all french lace units, but i was debating on going with a poly perimiter on my next unit. i've heard they are a little easier to attach and clean-up time is almost none. it seems to me the poly perimiter unit would be harder to remove since the lace release couldn't go through the poly. does anybody wear lace units with poly perimiter?? i would like to get some opinions and views on all lace Vs. lace with poly perimiter. what are the pros and cons??? i'm still trying to figure that out.
