After noting several currently disputed Pauline passages in Rom, Gal, and Philp, Henri Blocher writes:
A remarkable contrast emerges: whereas the new perspective strategy consists in narrowing down the issue, to zero in on what was really of burning interest to Paul, Jew-Gentile relations, Paul's strategy constantly seeks to broaden horizons and to bring into the discussion the more global truths of the gospel.
--p. 488 of "Justification of the Ungodly: Theological Reflections," in Justification and Variegated Nomism, Vol. 2.
That's one of a dozen or so equally helpful quotes from a chapter for which I'm very thankful.
