Recurve springs

Thanks. I don't know but maybe "top hats" with other values are hard to come by? I have 3 distributors here and they all have 15's in them.

The kit that 67Dart273 suggested looks good. Anyone have any experience with it? Good? Bad? I am more wondering if the limiting disc holds up.
