Ended up fitting S300. Chainline looks good, no issues.
Good crank, same or possibly slightly better than RD2 due to different type BB. (my subjective opinion).

Only after fully fitting S300 I realised that Oniums would be fine too but very tight. Turns out I was checking with only DS cup in and put the spider arm flush with the cup.
With both cups there is about 1-2mm gap between the crank and and bb cup which would give same clearance from chainstay to the spider arm.

Finally there is chainring nut wrench by Condor Cycles which works on S300 bolts better than Shimano or Parktool - this is for benefit others looking for info how to change chainrings on S300.
