In most cases about the only thing you need as a rig, is a basic knotless knotted or line aligned hook and hair, (some hook patterns DO NOT flip in with a knotless knot) rig that you can tie. Then if you have problems with hooking, or not or hookpulls you can change and adapt by playing with the hair or rig length. Also don't forget that how you feed or bait up and put in free offerings may have some effect on a rig behaviour. That is down to YOU to develop your own style.
Find a suitable hooklink material for you and the lakebed (!), but remember that you will have to possibily change this hooklink material depending on what you fish over as the various areas or lake you fish changes.
Those links above should help you immensely, but remember, MOST rigs are only confusing, because WE make them so. We fish the same every time, bait up same, cast the same, to the same features. When the fish get wary of that feeding situation, that area, that same lead set-up, then we change the rig, its the rig fault, not our own.
I've used this rig pretty much from 1994 to now, although I've used a fresh hook a few times and a fresh piece of braid a couple more, its the same rig
Why change what works? I'm comfortable with it, as are the fish in MOST waters
Rigs are only as confusing as you allow them to be.
I agree all the fish iv caught have been on simple rigs it just seems im missing out sometimes on more fish with the complicated rigs. Guess its more of a marketing product than anything else
