Just an FYI, I was speaking with the SA rep and asked about the guide wear. They test the line at SA by continuously running it through a metal guide material to measure the wear. What they found is that the regular line waers the guides faster than the sharkskin, likely because of the reduced friction.
He also mentioned that while he was testing the line over 3 days that his fingers suffered after stripping the line. If you use the line for any length of time, consider wearing a stripping glove or something.
