Don't really see the point. First the less resistance malarky , under normal fishing conditions there is no real differece between that and a fixed pat excepting a hook fixed tight behind the lead. Fish really aren't bothered by resistance, In\/ariably when using a 3 hook fixed pat the bottom hook which theoretically has the most resistance , has the most fish, in my experience. the second point about increased mo\/ement I'd also question as a fish hooked on a flapper isn't pulling gently but is swimming wildly from side to side imparting plenty of mo\/ement to the other baits.
far more likely to tangle than a 3 hook flapper or a wessex rig
