the difference is between the terms: soft systema and hard systema
and %-wise what is the application of each during a fight and what
does it depend on? In other words, can one be a soft systema expert
without being 'hard systema expert' and vice versa? Can one practice
only one of them? What is practicing Mikhail Ryabko on the tapes when
fighting the groups of people?

The next thing is 'rukopashnyj boy' - how is it related to the soft
and hard systema's? What I know for sure and for a fact is that
Kodacznikov wrote his book on the subject of 'rukopasznyj boy'
already in 1961.

My healing process is progressing and I am feeling much better now.
Few more days and I will try to excercise again.

Greeetings,

Mike
