If you are getting BBS two weeks into it I would say you are a 'quick study'. Good idea to get a second razor and I would suggest a 6/8. It has become my favorite size and it is close enough to what you are used to so that it won't be a big transition. A 5/8 is also a nice size. IME it is like driving a sports car compared to a pickup truck when compared to a 7/8. Anything below 5/8 is too small for my hand but YMMV.
