Uber, the buttons that Rad creates are the most comfortable in my collection, it was one of the first things I took notice of with my first pipe from him. Up until my first, I did not realize what I was missing in the comfort department. I never knew how much a buttons design could impact the over all experience. Now when I look at a new purchase, I look at the button very carefully.
Smart man! I too have learned to pay a lot of attention to the button area when I buy or make a pipe. IMO, it is the most important part of pipe design. Whether I reach for a pipe rarely has anything to do with whether it's attractive or not anymore, but is entirely dependent upon how comfortable it is to smoke.
