Very good advice.
Personally I tend to use more flipping jigs for most applications. If I'm swimming one and think the weed guard is a bit too much I'll thin it out. The added thickness of the hook doesn't bother me in the least, although the lighter wire hooks on a swim jig is a plus, but to me not necessary. I say this only because I use spinnerbaits a lot and the the hooks are ususally that of a flipping jig. The line tie is usually no more than 30* and the steam lined head will come thru weeds with very few problems.
Football jigs in chunck rocks really can't be beat, IMHO. The line tie is usually at 90* and really makes the trailer stand up giving a profile of a craw in a defensive position. At a dead stick, you can rock the head back and forth which has provened to be a great technique for me. The wide head bounces off rocks nicely and adds a clicking noise as if the craw is moving about.
The arkie is a great timeber jig. It's line tie is about 60* and has a wide head it deflects off timber. the trailer will stand up as well, not as much as a football head, but yet still gives a nice profile of a craw in a defensive position. It can be used in rocks as well, but I would avoid using this in weeds. It does work, but the flipping head will make the day more enjoyable, again, MHO.
