That's weird Pete. Like you, I've been trying to go a bit softer on the reeds in order to get more flexibility and a better bottom end. I used to play a Rico Royal 3, Plasticover 3, or a La Voz Medium. I play a RSJ 3S now and I find the 3S feels more like a Royal or Plasticover 2.5I vary between 2s and 2M, as opposed to 2.5 , but I always found 2.5 to be slightly too hard sometimes so it might be fair to say a 2M is equivalent to a 2.5
