I think the subject line is right on the mark – “types of runs.” In my relatively limited experiences, a lot of different things can happen: baits get blasted, thumped followed by the rod loading-up (common), thumped with very little load-up, load-up with undetectable hit, and totally undetected fish that moves towards you with the bait resulting in slack line.
As BK stated, never say always or never. Or as I like to say “Never say always or never, except you can always say “never say always or never!””
The thump or “thunk” followed bv some type of load-up is the classic flathead hit. Sometimes, live baits get obliterated by the fish and it ends up being a 4# channel cat. That can be fun too!
My general experience with channel cats has been the bigger ones are a little slower on the take than the small to medium sized ones…
