I have the Woody Shaw set on vinyl and I have not noticed any adverse effects on sound quality. The longest side is the A side with 19:28 minutes, which is nothing unusual. As mentioned earlier, opposite to the information given on the cover and on discogs etc., "Diane" is part of the D side, not of the C side. The sound (and pressing) quality of this set is very high. My only criticism is related to the use of paper inner sleeves (which I immediately replaced upon receipt of this set).
