Problem! Which Nose Piercing Jewelry?

I've had my nose pierced for a little over two years now and I've yet to find a comfortable stud. When I was first pierced, my piercer put in a bone. Two weeks later I read online that bones have to sometimes be surgically removed in the case of the hole closing too tight around the ball at the end that keeps it from falling out. I took the bone out and replaced it with a "L" shaped stud. I became very frustrated with the "L" stud because it was always falling out and also I was constantly having to turn it back in place so the "L" was poking out of my nostril all the time (looked like a was picking my nose!). When my piercing was 6 months old and healed properly, I went to a different piercer, told him about my problems with the jewelry and asked if there was a different kind I could try. He gave me a screw (which looked pretty intimidating), but I bought it and after an hour I finally got it in. Same problem. The screw doesn't fall out, but it doesn't stay in place either. I'm constantly turning it so the jewelry isn't poking out. Does anyone else have the same problems and/or a solution? I really don't want a ring, I'd like to stick with studs, but I'm so sick of looking like a have a metal booger poking out of my nose!
