Any suggestions on filter holder that can be used with Cambo SK Digitars 35/5.6XL and 72/5.6L... WITHOUT REMOVING THE BULL BARS? I have the Cokin P-Series, and it doesn't fit within the bull bars. I saw a post from Don Libby concerning the Lee RF-75 working with 72mm and 120mm lenses, but not the 35mm.

Any alternatives to removing the bull bars?
