I'm with Atimm on this one. I've used weedless jigheads for well over 30yrs (casting).
One of the biggest mistakes made, that causes a lot of snags on wood cover, is trying to jerk the jig over or off the cover (even when using a weedless jighead). What usually happens is you just dig the hook deeper into the wood, and if your line isn't strong enough to bend the hook open ... then it will likely break.
What I do is constantly watch my line as it comes back towards me, which tells me two things --- I got bit (line jumps or moves oddly) or the line is no longer inching its way towards me (line is running over some obstacle). When I see the second thing happening, I start to pay even more attention to the "feel" thru the rod tip. When my reeling in starts to cause the rod tip to start to bend forward, I stop reeling, as I know that my jig has come to the object that the line is running over. I simply drop the rod tip about 6" and watch for the line to straighten out, indicating that the jig has dropped down .... then I lift (not jerk) the rod tip about 12" and hold it there for a couple of seconds before dropping it back down to its normal position and begin reeling again. That is unless I get a hit after bumping the jig over the object ... which does happen on occasion.
The deal is ... the jighead is weighted so that the hook is pointing upwards on the retrieve. When an object is encountered with the line, and the jig reaches that object, the weight of the hook causes the jig to fall over and that makes it more likely for the hook point to come into contact with the object. What I do is simply let the jig fall back away from the object and then the lifting of the rod tip twice that distance will cause the jig to "bounce" over the object (with the hook pointing up) and then start to pendulum swing back towards me. And like I said ... I tend to kinda "go on point" when that happens, because I've had many instances where I got a hit once the jig cleared the object and began falling/swinging back towards me. (musta got their attention or hacked them off
)
And NO, it doesn't ALWAYS work
... so, when it don't and I can't get the rod tip on the other side of the snag & pop it off, I just usually break the line or straighten the hook pulling on it.
I use the Improved Clinch Knot, rather than a loop knot, for the simple reason that I don't want that "loop" to be the first thing to hang on the wood cover ... and when I'm casting a jig, 99% of the time it's towards some form of wood cover.
