I'm not going to get all technical ,here's what I've learnt over time ..
I had an old friend 'Egloskerry Tom' Tom had a massive influence on me as a youngster ,as far as carping went he was God..
I used to watch him set up a rod ,cast his latest rig out ,with the latest homemade RH recipe, Partridge hook ,then came attaching backleads ,sinking the line ,....you get the picture !...a right kerfuffle!..
He didn't catch many ,but I loved him as a friend ..
Anyway I used to turn up with a bag of Richwoth tutti, some not looking to good ,just found some ,spots that I felt held fish ...one Sunday I turned up he'd been there hours same routine etc ....and nowt ...by lunch time fishing simple running rigs and so on I had 7 nice carp...what that taught me is over complication looses against simplicity ..
I fish similar even today, simple is best ,no gadgets or gimmicks ,just a sharp hook in the right place carp are simple creatures...if they don't feed there is nothing you can do about it...and boy ,don't those tackle manufacturers know it they play on people's insecurity..
