The consensus on resting after seems to be that it is a wives tale. If you like a bit more weight then the 6/8. I also find the larger ones need the lather cleaned off less while shaving and easier to see the angle on my face. But again everyone has different preferences. I also prefer a hanging strop and find smaller than 6/8 a wee bit awkward on the strop. Aust will be a good razor whichever you go for.
