I'm not too sure on either really ... :?
either they are exposed or they aren't ... if you are wanting to make them visible then exposed doesn't cost anything

the carbon one looks quite awkward ( like big bug eyes ) and the clear one looks a bit rice car show for me ... if you are wanting to adjust your cam wheels with these you will still have to remove them for access ... keep it pure
lightweight expensive CF cover for adjustable "exposed" cam wheels just doesn't make sense to me :roll:
sorry to be negative but I just think that nice functional and beautifully engineered parts like those cam wheels don't need tarted up with any carbon or polycarbonate fluff :lol: ... carbon or polycarbonate have their place, don't get me wrong I just don't think that it is there
