Just my humble $0.02....

I have a Dovo Flowing (essentially a fancy Bismark) and a 7/8 Aust Spanish tip. The Aust wins by a long stretch. While I love the ergonomics of the Dovo, it has proven to be one pain in the behind to hone. It came to me a decent edge and it has seen a fair amount of use, but when it came time to refresh it, nothing seems to work. The Ralf Aust has been in rotation for some time as well, and has seen the stones once or twice.. it takes an edge with ease and shaves like a dream.

Pair them up and the Ralf Aust wins on all counts (even with the cheap plastic scales).
