When using live Brim on either a rod or a yo-yo- where is it best to hook the fish, at the tail,back or through the lips, top to bottom or bottom to top, what size hook for average size cat?

Do u suggest the circle hook and any particular rig.
Does it matter if the rigging (leader) shows much?

New to this and any help appreciated.

Also when you do catch is it ok to ice them down and clean the next AM.

Thanks
John
