Compared to the ALU, the Rough are a little bit less durable.
Also, as far as the debate on textured / shaped strings adding more spin to your shots...There was a study that showed that it adds maybe 1-2% more spin.
Some people swear that they get way more spin than that but its merely a mental thing where they forget that since they think they are getting more spin, they are actually really trying to hit with a lot more spin.
Different strings types (eg. nylon, poly, etc) vary much more in spin potential however.
