well never faulted mantas, I mean some of the extras strong as.
do blunt easy but hey- all the chemical hooks do.
lost a fish this year which had a head like a football, could of blamed the hook, but to be honest didn't have a chance as it was just half lipped.
I have been impressed with some of the offset hooks on the market which actually catch the side of the cods gob. get one hell hold. only down side is once there in a snag, say bye bye to shocker
never tried the power worms mind have to say
