I currently use a 5/8 dovo singer, if I were to get a newn a razor and wanted to get a thicker razor, what would you guys suggest: a 6/8 or 7/8? Would I be able to tell the difference between a 5/8 and 6/8, or should I go for 7/8? Also, what would you guys suggest for a good second razor, that would be similar enough to the singer, but something different. I am thinking about x-mas gift for myself...
