Steve, that is a very tough question to ask and it really depends on who you ask. In all the shooting and testing I have done, if I am using MWB, then I do not use the Red filter. I would say its one of the most discussed topics...and as much as I would say do it my way, I think its better for you to see which way you like best for your style.
Good luck and happy shooting!!
