I recently submitted a portfolio of 35mm B&W prints enlarged to 8X10 for membership in a gallery. They basically liked my work and accepted me for an associate membership. Not a full one. That I needed to improve my work technically. One of the technical comments was that my prints didn't give the impression of sharpness that they could. My grain looked "mushy" and lacked accutance. Also that my tones were "muddy". The person I spoke with said the reason was the D-76 1+1 I use with the Delta 400. He suggested I keep the Delta but maybe rate it at around 200-300 and try either, Microdol- X, HC-110 but didn't say which dilution or Rodinol. After looking at some other prints in the gallery he pointed out I would like to give it a try. Although some had a very salt and pepper look which I though a little too drastic for my taste. Any suggestions as I would like to keep it simple with developers I can readily buy. That's why I originally chose D-76. I asked this question elsewhere and received confusing responses.
