I’ve had to replace a tip top guide twice on a 7 and 9 wt using regular lines. Now all my shooting head rods are all ceramic guides (no guide wear at all ;)). My SLT 5wt guides are starting to show bad wear using standard FL lines. If Sharkskin holds more dirt for some reason then it’ll erode the guides worse.
Streamer fishing usually does put the line in the exact same place on each retrieve. The tip tip takes the brunt of the punishment.
All I hear is that you get to fish waaaaaaay too much! ;D
