One of my Super20s alto was repadded some time ago with white (kanga)roo pads and Maestro star resonators. They looked very nice and soft and the saxophone was playing perfectly. Unfortunately I have not played it much because after some time, probably due to a poor craftsmanship, the saxophone started leaking. When I've checked it I realized that some of the pads moved (probably due to the kind of clear glue used) from their original position and also that there was a strong and deep circular mark on them corresponding to the tone hole diameter. I don't know if you had the same experience with the brown ones.Anyway I always use shellac to glue pads and I will continue using it. Just my opinion of course...
