Lens shade for CV 35mm 2.5 classic

[Santafecino]

A question for folks who use the CV 35mm F:2.5 on Leica M's. I use the LH-2 lens shade, and it works much better than the little ring shade that comes with the lens (especially when using filters), but it intrudes a lot into the lower right corner of the viewfinder's field. Is there a better solution?
Thanks,
