The best thing I like is less black rubber on your rope. You still get alittle discoloration but not like the old inter tube rubber. I have been using the "Classic" pre cut rubber. The strips tend to roll and twist and Iwas always breaking the rubber at the base of the horn. My rope would sometimes get caught under the rubber at the base of the horn, this has never happened since switching to ProDally. The ProDally tends to grip your rope better causing your rope to run less. I feel this would benefit the team roping industry.
