the answer i gave in another thread, but to complete this, i ll post it here again.
this time i Play 4-5-1 v in each match. i begin with normal, flanks, strong pressing, short, hard/ normal, zonal. red on dl and dr and sometimes with offside trap. in some cases i Change my arrows to aml and amr (sometimes +st).
the 2. Option for 4-5-1 v is normal, flanks, low pressing, mixed / Long, hard/ normal, zonal. sometimes + Counter attack. red on dl and dr or red on aml and amr (sometimes + st).
in 3-5-2 v you only Need the arrows in most cases on aml and amr. sometimes only 1 st, or 1 st and aml or amr
I have not tried it with system
there were seasons where i had played 10-15 friendlies in a day to learn and find out how some formations work
