Can't go wrong with a wicker bill.i like how it looks aswell.I did the Wicker Bill too.. Was reluctant because I wasn't sure how Id like the "tacked on" look. Then I had a look at the factory wicker bill on my brothers C7GS and realized that the wicker bill IS a tack on so it looks just like its supposed too look.... lol.
Anyway, I bought the zl1 add ons standard and then sanded and polished the edges myself and it turned out great.
Pretty subtle visual upgrade that doesn't try to mimic the "R" (my other choice was the R wing)
Overall very happy with it.
