I agree that plastic pitches , no matter the quality will never be a subtitute for a GOOD QUALITY grass pitch.
But which would you prefer, Motherwells pitch from 2 years ago , Tannadice sand pit from years gone by or Todays surface ( which i believe is the same as the pitch at Ralston)
I can fully understand why teams from the lower leagues install plastic, lost revenue from cancelled/abandoned games can cripple these teams so from that angle, plastic 4g ,5g or whatever makes sense.
