no contest the STS is superior except maybe in tough cereal conditions.

I never change concaves. Harvest peas, lentils, wheat, durum,, flax, mustard with the same set. Only thing I do is throw a set of filler plates in the middle concave when doing smaller grains and pull them out when doing peas. Seems to work very well for us. I also agree with keeping an STS full at all times.
