Sorry Jmin44 I cant agree with you yes I know the PVA can contract to the point where it can explode. But really it just does not happen that much. A rig with a long soft braided hair if not locked in place with some kind of PVA bag or nuggets will always tangle no matter what you do. So the PVA has got to be a far better bet.
Re The chod rig if it is a true chod rig it should be made with a stiff bristle filiment mono or Flouro this set up will never need any PVA bags to wotk properly, PVA nugget maybe but not PVA stocking bags. No wonder it all went wrong the guy obviously does not understand what a chod rig is designed to do.
Who is saying lots of bait catches fish ? PVA stocking bags can be as small as 1/2" diameter thats about the same size as am acorn of bait thats not lots ?.
This is a partially finished chod rig you can see the stiff mono hook lenght when a boilie is placed on the hair the stiff mono will not allow tangles
