I had the rapid kit in my old 14 and it was very easy to do. Here is what it looked like with 8 blue and 4 white. I wanted more of a blue look but had to keep the girl happy
that Rapid LED looks like a nice kit....all I'd add is to be sure to buy the dimmable version no matter which you choose...
imo the dual drivers are a big advantage because it will allow you more flexibility with your color spectrum...
