Thank you all!
This is how the sandblasted Natural looked like after some love:
I shortened the top cap a bit and opened it up a bit to a 2,8 mm hole. The RSST sits on a Fusion Mods SG-1 to get the hybrid look. I was very happy with the result and its a good mod. It has the Tapas drip tip on the picture and I think I will keep it like this.
