There is a good variety of feathers in the store and all will catch fish. I carry an assortment so I can try different patterns on the day. Like any fishing tackle what works one hour may not work the next so for the time they take to unclip them and the cost they’re worth having a variety in your tackle bag.
Here you can see different patterns and hook sizes with the daylight style having 7/0 hooks (3) and they will take large pollack and cod, get two or three good size fish on them and you will know all about it.
