I know this has been covered before but i believe the baits have been updated.   They now come with black vmc size 6 hooks.   I was thinking of swapping them with kvd triple grips short shank size 4.    Has anyone done this i am worried they will get hung up more

Put the KVD's on and see if they tangle.  You really can't tell whether a set of trebles will fit w/o tangling until you try them, but the KVD 4's often work just fine in replacing #6 trebles.
