nose rings are a ring...I don't know if they are any easier, more of a look or comfort thing.
I have always used screws and I prefer them because they stay in better then an L bend and are better then a straight post (evil).
You can get a piercer to custom bend a nose screw for you but it has to made out of metal. I have a bioplast one which is a plastic substance and mine can only be cut on the curve not on the post which sucks coz thats the bit thats too long for me.
