trying the Paisano W.B. / Burgundy N.F. linkup? I belive that is IV 5.9, per the Kearney Guide.
Yeah - it's a nice looking line but Burgundy was not on our itinerary when we set out (all we had was partial N&P description for N. Face ONLY). This way you replace the initial ~400 feet of chossy 4th-low 5th climbing on N. Face route with quality stuff on Paisano I think.
