T-Ken is right. I'm not a fan of rail-less. Especially on 1st gen white - makes it look like an egg. And, I prefer black rails over aluminum rails 90% of the time.
But your (Hollywood's) car is different and has been for a while. As it is now, I like the alum rails. With your plans of a black roof and lowering???, I say definately go rail-lesssssss. I'm excited to see your new look.
