zip grooves/lazer milled

after some new clubs ,( sold my old 1s wilson di11) been useing my mates spare clubs cg7 they r GREAT ,so been looking 2 get a set ,but the zip grooves look abit worn out ?, how long do the zip grooves//lazer milled face lest ??? or will the newer cg 16 b best , p.s i play alot , + another p.s has anyone got the cg16 and how do you find then

I've got the CG16 60* wedge, fantastic club. That's laser milled and although it seems to scratch easy, it still performs wonderfully.

thank you ,
