The fact that you already caught fish on jigs is a big help since you know what a bite feels like. And to me it sounds as you're looking for different ways to fish them and I can help a little bit. Try stroking a jig, it is usually done with a jig no less than 1/2oz and while there are propably a few different ways to do I know only my way and it works so if it isn't broke don't fix it. To stroke a jig you make a long cast, presumably to open water with some type of fish holding tructure or cover on the bottom. Once the jig hits bottom rip the jig off the bottom, I like to move my rod from the 8 o'clock position to the 11o'clock position, and then follow it back down letting the jig fall on a slack line. You will get a variety of different types of hits using this method, sometimes the line will jump, other times it moves off to one side rather quickly, these bites typically happen as the jig falls but when the fish are active you'll feel a solid thump but on the way down watch your line. I don't know how deep your fishing but I found this works best in 25' of water up to 15', I won't stroke a jig any shallower than that. I used to use a hula grub as a trailer as you want a trailer that has action but ever since the Rage craw was introduced it goes on the back of all my jigs used for stroking. For the football heads I just drag the jig slowly on the bottom, a few feet and stop then a few feet and stop, nothing special but the mop jig is different even if it has a football head. The mop jig is designed to create a larger profile but the big skirt can attract fish as well as just making the jig look big, and to get the most from it I fish it using short hops. When the mop jig hits bottom I let it sit motionless for about 5 to 10 seconds or so and then I hop it, lot lift and drop but hop it by moving my rod from 9 o'clock to 11 o'clock pretty quickly and then let it sit for a few seconds and repeat, what you are doing is making the skirt move even when the jig stops because the skirt will become tight together on the inital hop but it only goes up a little bit but when the jig falls it stops dead and the skirt will then begin to fall and indivdual strands start to dance as they make their way to a stable position. It is pretty neat when you hop that jig like that and about 3 seconds after it hits you get that thump, it really is a fun way to fish a jig. As for you losing fish, it happens but a lot of it has to do with how the lure is fished and how the fish takes it. What you need to do is worry about the hookset the most, I suspect that may be what you problem is as I had the same sort of thing happen to me a long time ago. When you get a bite on a jig, you must reel up the slack before setting the hook, if you don't most of that swing is for nothing as all you're doing is picking up line and only a small part of the swing is actually driving the hook into the jaw of the fish. Sometimes it is reaction, it was for me, you see the line move and/or feel the thump or tap and you swing and next thing you know you're fighting the fish and as quick as he was hooked is as quickly he is gone. Make sure your line is tight and try to avoid snap sets as you can break your line as well as just losing fish. A snap set is almost the same except right before you swing you drop your rod tip down and then "snap" the rod up into the hookset. It is harder to do because that instant you get the strike you want to pull that rod back but you need to remember to reel up the slack and then smoothly as possible begin your hook set and try to avoid lowering the tip and snap setting as your hook up to landing percentage won't increase that way either, good luck.
