I believe all drifters came w/silicone pads. The Duncan stickers will have a cloth texture under the coating, it may be visible under the coating when new, but you will definitely see it when they wear. The silicone pads have no texture. The Duncan stickers will wear quickly, the silicone pads hardly at all with extended play.
Cool, thanks for the info. Yea, my pads are not not cloth-y, they are pretty "rubbery".
So, Ill try a Terrapin FHZipp bearing in my Drifter. It looks like the Zipp bearing is a mm wider so that should give the Drifter a better gap to make it less snaggy and hold more layers of string. Ill report back when the bearing arrives. If I like it, Ill probly get some Terrapin C sized bearings too!
