howdy all, i just got done reading colin kageyama's book "what fish see" , copyright of 1999 so i don't know if this ? has already gone thru the gamet of your collective knowlegde. but here it is--has anyone ever tried the 6"see best" filters he talks of in the book? if so what did you think, did you try them, did one color truly work best given the water color and clarity? the pictures in the book raise many ?'s in my mind. if any one has these filters could i rent, try, or lastly (if affordable)buy them. thanks c.b. :cheers:
