Skip Input Mesh if spline has too much bend

[Zilk1]

Just bought the tool and love it, started using it to create pipes for environments and had some different variations to randomize between. However found an issue that would be neat to be able to solve, if the split has too much bend I would like to ignore some mesh variations from the input meshes.

Is there any way to do this? Otherwise a Max tangent size or something like that would be awesome as setting for the properties section for each mesh in the Input Mesh script.
