Thread: Hart 6/8 or 7/8

So I've decided as a Christmas present to myself to get a hart razor. I'm getting pretty comfortable with my Dovo 5/8 and have had a few months of experience.

I'm wondering if I should get a 6/8 or 7/8 hart. I have a very course beard with sensitive skin and plan on using it for a very long time (I'm only 18). Which would yield the best shave and would retain its overall quality the best?

I'm leaning towards the 7/8 but have heard complaints of it being too heavy. Any advice would be very much appreciated.
