I opted for both on my Metallica. I just got the PS lights yesterday and plan to install them today. Joe should be shipping my PowerBladez the 1st week in December so when I get them I will install asap and post pictures here for you. I'll do one of each and then together so that you can get a better idea which way you or anyone else want to go... that is if you're patient enough to wait that long, lol. Cheers.
