Heck, I have a hard enough time seeing the image to focus with all the magenta dialed in on my dichro head or using the #5 filter. If using a tri-color blue filter is worse, I'll just stick with magenta

Need more contrast? Change print developer, bleach back the print a bit after printing heavier, bleach-redevelop the neg, etc. (including developing more the next time). I don't think we should be using max contrast on VC papers that much anyway...
