but i find the statement that a simple mono rig as the be all and end all of rigs ,
I don't think anyone is really saying that Chris. Posters that don't use a combi rig have obviously never found a need for it, but maybe their results might improve if they did. Conversely there may be anglers who always use a combi rig when they actually have no need to. I think the OP was an excellent question (thanks) and has raised additional questions, as all really good OPs do. It's 'horses for courses' and all good anglers keep an open mind, IMO
so i get a bit defensive when some posters suggest these over engineered rigs are unnecessary and not needed when in my humble opinion they are in some circumstances
I think the 'over engineering' thing is a different question. The 'combi-bit' is just one part of some rigs, and I fully accept that that 'bit'
may be beneficial in
some situations. But beneficial in all situations? Maybe, just maybe. You'd need to have one of each rig cast to a very small area, at the same time with the same bait, and repeat that exercise many times ... to run a good experiment to find anything close to a definitive answer.
The only point I'd stand firm on is ... I personally feel the need to be able to justify to myself every extra bit of paraphernalia I add to my line. I'd be thinking to myself ... "Why am I adding that? What
problem is it solving? Can that problem be solved by a better and/or simpler means?"
But before any of that, there will always be the question in my mind "Is it fish-safe". If it ain't, if it weakens my gear/rig, I won't use it.
N.b.. I used to fish the Teme up to 5 to 6 days a week and never used a combi there. But, from Hatter's feedback, I believe that Sue Anderson (Mark's [Admin] wife) always used one. Going by the success she achieved then she'd out-fish me most days. Was that down her rig of choice, or just better watercraft? Dunno.
