I started carping in 79' back then both KM & RH books, plus the monthly fishing mag articles both hammered the High Nutritional Value theory as the way forward...it wasn't until I read a fascinating article mid-80's in BIG FISH Mag by Clive Dietrich (richworth baits, i still have that mag in the loft!) about low to mid-protein baits, brilliant piece, i kept that articles theme in my mind over the years... what i bolded above is SPOT on (similar views as Clive's article) in regards to how i make baits today
