i ware the french lace with the poly sides and back. its a good piece for durabilty,(around 6 months) is taken care when removing and rebonding, although i find at toplace,if you order the same configureation, the poly thickness vary's , as does the density, and 3 out of 4 for me the knots wre not bleached,this really shows up if you have the 64 french lace. so scream , yell and shout, you want all the knots bleached! this is what i have been doing, but i still get just the very front bleached ,sometimes your just a number on a invoice (me)
