My self I use all three materials fishing in making up stuff, feathers hair and also plastic. as far as which one catches more fish, it depends on whatever they are hitting some days they want very little action which their hair has just a vibrating up to trigger them other days they want more action so I use plastic. Maribou has a lot of action in it and I use quite a bit of that. Just depends on the fish. Also, I use a lot of hackle..
