Re: heavy wt. injuries
I get sore sometimes casting and fighting fish. A TiCR X 7wt and several good sized carp and cats will leave one quite sore.
Another instance of being sore was when I first used my switch rod out on the river. The fish were biting very close in and I decided to one-hand it all day like He-Man. Didn't even think to roll cast it. Now, when they're close that's usually all I do and I can cover a lot of water. Farther out or in some current, I'll do some spey casts. But, I spent the next day nursing my elbow and shoulder after that adventure.
