Welcome to the board Coolhand. Aftershaves (a/s) are one of the more personal decisions in wetshaving and everyone has to find what works best for them. That said, since you have access to Proraso, I would recommend their After Shave Liquid Cream. Its cheap, works extremely well, and has minimal scent- clean and soapy. I've heard good things about their a/s splash, but never tried it. In the end, you'll want to try a bunch of stuff and see what you like.
Enjoy!
