I personally would go with the latter. But it's not a big difference.
Margo, thank you, I had hoped you would see this. The 71.5 deg head angle with 50mm rake is what Waterford is recommending for my Gunnar custom build. It appears to have a trail of 54.7 if my fitter has recorded this properly - is that possible with the given head angle and 50mm rake? I do not know what tire size they are assuming for the Gunnar. The basic design is based on their cross frame, and they are recommending an upgraded Waterford road fork (for weight, and I won't be putting racks on this bike).

I am looking at some hand-written notes he gave me that compares the custom specs with my LHT - and the wheels are indeed 26'. Both chainstay and wheelbase are quite a bit shorter, if that matters.
