TK, if you ever get the chance to compare russian joker to many other types you will notice that virtually no russian bounces up and down in the water, whilst belgium can have joker coming 6 inches off the deck. This can dictate the depth of which you will catch roach (or the better samples).
I would deffo feed all lines but have two negative ones just in case you are not on roach ! Why not have a caster line down the track with a bit of raw.
I think the answer to a bread and joker line at 10 and 2 should depend on the consistancy of bread on the venue. If it is good then do it, if not, a small and moderate to good feed of joker on the two lines instead.
A small leamed up ball at 4/5 m if you expect perch, up the joker content if roach.
If struggling put a small leamed up ball with not many joker down the track opposite to the caster line, to mug a few perch.
Try a white caster every now and again as big perch love em.
Sorry if I have taught you to suck eggs !!!
