The 1/4 Swim Bait head and the 3" Ripper are like peanut butter and jelly. Great combination. I use them on Lake Michigan so I have slightly modified the eye for a 1/0 EC635 and its perfect for the 3" Ripper. When you put the point of the hook into the Ripper, insert it slightly off center towards the belly so the belly plastic clears the "skid-plate" on the jig.
The 3/8 head is perfect for the 3.5" Ripper.
You will like that mold!
