Ethan:
Welcome to this side of wet shaving. I own a Ralf Aust 7/8th's full hollow and it is a very good razor, it was paired with a Hart 6/8th's 1/4 hollow as my first pair of str8's and that's what I got started on.
Like others I have now owned many different razors, different sizes and grinds. My advise would echo AG's with the addition of getting two shave ready razors to begin your str8 razor journey as many of us were hard on our first edges as we learned to shave and strop. With two razors to work with when you dull the edge on the first one you will have a second to shave with while the it's mate is out being honed, this way you can continue to practice shaving, stropping, lather building in a continuous manner.
