I am thinking about getting either vortex frame sliders or DP LED flame sliders for my 2005 f4i. Two questions:

1) For the vortex sliders, do I need to buy two different parts? Spools and bases? And it looks like there's a choice ranging from 6mm-10mm? What size would be best?

2) What do people think of the diamond powersports flame sliders? I'm wondering if it would like kinda weird to have sliders that light up but I'm also thinking it might turn out looking kinda good

Thanks
