Just thought, I only use 16mm pop ups on this rig. Bait size my alter the hooking potential, I don't know for sure. Yet my mate he always goes against the grain, 6oz leads, 12inch or longer hooklinks if most are using 6-10 inch hook links and his pop ups for this rig are 20mm and he nails them also. My mate is currently fishing dinton and he will not use any other rig since he's gone over to this. I think in the 4yrs he's been using it he has only ever had 1 hook pull , which on a lake like dinton or any lake for that matter, you don't want hook pulls. And he always tells me how they were nailed when he goes to unhook them.
