Hey Shakespear..lol. those are all proper rigs, come on fox? lol! they do work, but you need to understand where they work,its not just a case of thinking hmmm this one looks great and dumping it into a dam, they all designed for diff conditions, mainly, baits and dam bottoms, gravel bars, weed patches, silt and deep muddy bottoms. I just have a problem with the ones they burn, its so easy to accidentally catch the hook link. Also, im a bit wary that a bfc would pull the burn ball through the eye and then hes gone.
The best starter rig is the straight forward type, sim to the no 6 in the video, a simple wide gape hook with a hair using the knotless knot. and if you into helicopters that fine, they kinda universal. just remember to adjust them correctly for the diff bottoms fished. Safety clip types are also very good.
Do yourself a favour and buy a book "Fox guide to modern carp fishing", found at tackle shops about R150-R200 good investment, you can learn about the diff rigs there and they show you how to make them up. Read and practice... all I can say, and then find experienced anglers to go with you or help you... he he heeee!
, cheers and enjoy your day
