beware - less can be more sometimes 
I agree with Kraut on less is more.
When you see factory lowers on CVO's, they tend to be just one solid color. I know lots of guys added lowers to the '09 SERG's as well as King Tour Paks. Most incorporated the paint striping from the bike to the lowers and the tour paks. I still prefer the solid lowers and the solid tour pak without the integration of the striping to either.
For me the striping separates the upper from the lower and with the striping added back into the lowers and tour pak, it gets just a little busy for me.
I like what the guys, Larry B etc, have done with theirs, but to me, less is more.
This is why our bikes are what they are. Everyone has different opinions on what they like and do what they do according to their own ideas.
You probably can't go wrong either way.
As far as the rear of the tour paks go, I do want to add a bit of something in script to that, but still not certain of what.
Good luck with your painting ideas.
