You must climb some really, REALLY steep hills. Even back-in-the-day (1970s) when I lived and raced in ultra-hilly Fayetteville, Arkansas (
GO HOGS!) I
never had my Campy NR upshift on me on a steep climb. However, it sounds like you solved your problem (I've always heard nothing good things about Simplex Retrofriction shifters).
