Yea you must be right.

The funny thing is that i'm complaining since 2/3 months, and i could do 2 different templates with this delay.

Do you like the temple flaps on your custom piece ? It has to be less dense, i have tried to cut temple flaps from an old piece but it's very difficult even if i reduce the density, it looks a bit weird, the look is acceptable to go out on the street, but not to take the metro or tram !
