Start by saying I use neither so take my opinion for what it is worth. I use a L7 Classic valve with stock Classic on/off. However...I have a friend
I have one that is setup for a classic rt. It has had some milling done to it. I'll shoot you some pics if your interested.
This is where I ask for (insert ridiculous fade here)
Gloss black, but I can see why you might avoid the hassle
