New Brakes, which fluid?

So I just got done rebuilding the entire brake system on my 1953 M38A1 (Stock configuration) Everything new from the master cylinder to the brake pads including all hard and soft hoses, tees and wheel cylinders. So essentially I'm starting with a completely empty system. Any thoughts on what kind of fluid I should use. I know there's several types and you should never mix them, so since this is a new system, any benefits to one kind over another? Thanks for your input!

P.S. Is the search function down? I got an error message when I tried to search for brake fluid.

 

Oops! Also, I bought one of those vacuum pump brake bleeder tools at Harbor Freight to bleed the system, has anyone had experience with these type of pumps? It sounds like a pretty slick one-man system, or is there any pitfalls! Thanks again.
