Proportioning Valve II

I know there was another thread about proportioning valves that touched on the issue, but I'm looking for more direct input on a specific question.

I had manual front and rear drums and have recently upgraded to manual front and rear discs. Now I've heard from one person that it's foolish to use a proportioning valve because there is no need with manuals discs, but then I hear from a different source that I'm going to have a lot of trouble stopping without one.

I need to know who to believe! I'll be doing the brake lines soon and I need to know what I have to plan for!

Thanks everyone!
