If you're in a current situation, the fish takes the bait & runs upstream, so you don't even know you've got a hit until it's swallowed the bait. That's one plus with the circles, it will slide out to their lips, maybe even all the way out & you hook water !!
I'm fishing from a boat usually from 35-65' deep, so it's a different ballgame if you're on the bank in a snag area. Depending upon conditions, one hook will be better than the other. I carry a good supply of both with me at all times.
I've actually caught several fish I didn't know were there until I checked my baits, I do that frequently. Saw it on show with Doug Stange, he said to check your baits ever 5 minutes as they might roll under a rock or something. What I do is just crank it up a turn or two, every 5-10 minutes, then after about 3 times, check the bait. The current will degrade it banging against the rocks, and small fish will chew it up too. Sometimes when I reel them in, they are under or upstream of the boat with a fish on !
Hope we can have that happen for you Jack !! It's a kick !
