I primarily use solid body jigs because historically I have been skunked on tube bodies.

My question is, when using solid body jigs, is it generally better top use jig heads with or without a collar? So far I have been using bass pro unpainted heads with the barbed collar and find myself having to slide the body back up onto the collar relatively often.

I am looking into buying some better quality heads, but the abundance of styles has me a bit apprehensive on what to get.
