Looking at my first straight razor. Ralf Aust has come recommended, but at SRD the 6/8 is twice as expensive as the 5/8 model. Lynn recommends starting with a 6/8 full hollow. Any thoughts on this? Is the basic Ralf Aust 5/8 full hollow okay to start with, or should I look for another make in a 6/8 that doesn't break the bank?
