The recommendation in the FAQ is just that, a recommendation. Whether you choose a 5 or 6/8 will not make too much of a difference, anyhow. I find the bigger blades visually more appealing, but that is really all. As for the grind, hollow grinds vary, too. I personally find the Dovo 'Best Quality' a perfect starter razor (price vs performance cannot really be beat), but I would - for now - steer clear of singing full hollows like the 'Prima Klang'.

If you really want a thicker grind, our Classifieds or even Revisor's 'Rarität der Woche' might be an interesting place to start.

Happy shopping,
