To be frank, if you have never done B&W (or even film) before, better first start with a 135mm and try out first.
After which you should spend a few months doing 120. These will build up the basics.
LF is doing everything yourself from scratch from basic. If without basic want to 'fly' then you will find its no fun at all.
Then will give up very quickly, and wasting time and money.
I have seen alot of people gave up just doing 120. There is nothing wrong to give up, but its better to start from primary then go stright to University.
