How about loose springs on a Graphic spring back? The ones on my Speed could use a bit more tension - no big deal, but it annoys me.

You can re-arch those. Remove them and carefully bend just a little at a time along the entire length until you get what you want. Gently is a good word to use here. You can also add a little stip of metal under the center screws. 1/4 inch wide X 3/4 inch long X 1/32 inch thick adds a lot of tension.
