Makes a certain amount of sense.
I still tend to use SB on particle balls that are supposed to be softer (Storm, Track, Columbia). Odd as some SB pads, depending on the grit, actually use the same abrasive, silicon carbide, as wet/dry sandpaper and as Abralon.
FYI another well-respected driller/pro shop person here has said that Abralon seems to provide a smoother finish than the equivalent wet/dry sandpaper. That might be that foam backing playing an important role. I haven't seen that myself and I am always cautious about pressing too hard or for too long on/with any abrasive for fear I may be taking that abrasive to a lower or finer level, resulting in too smooth a surface on my bowling balls.
