Thanks guys. If I go forward with it, I'll definitely be going with the S-Tune kit.. I like keeping things simple and going with the Duraflex adds too many variables just to save a few hundred bucks. The extra cost in the end will be worth the saved stress and effort in doing the install.
As for a yellow S-Tune here are a few pics of ones I've come across on this site...

but my overall goal is to do something similar to what Smallywood did with his Platinum Graphite...

Really love the Red behind the Nissan Emblem. Going back and forth between the Sport Spoiler or the S-Tune Spoiler...
I have plenty of time to decide...
