Dan. I started spoon fishing 4 or 5 years ago because of some of your posts and the success you were having with it. Swinging spoons I'm fine with but could you explain your jigging technique and the type of water you would use that technique in. Do you jig your spoon back at the end of your swing ? Also seeing as you use a spinning reel do you let line out or let your spoon flutter down stream if the current is too strong to keep your spoon near the the bottom?
Jigging can be used in a variety of situations.
I typically use it in pockets or seams by casting upriver and then jigging as it comes back towards you (mostly just pop it along bottom, I give a small jig up every time I feel it touch to prevent snagging).
Its also useful in deep, slow pools. Cast way up to give it time to sink and then jig it along down deep.
Sometimes, I'll even jig in the same runs that I'd normally swing in. Imparting a different action can sometimes provide a hit. I often observe the fish too. If they are showing interest but not moving far, casting up in front of them and jigging it as it comes down their "line" will often pick them up.
As for letting line out, I never do. I just adjust how far up I cast or how heavy of spoons I'm using. The same is true for swinging.
