I haven't seen a mountain road yet that I wouldn't ride either my Trek 520 or my LHT down, and probably drop a lot of roadies on the descent.

You specify mid fork eyelets, that's going to give you not that many stock bikes to choose from.

Bianchi Volpe, Trek 520, There's 2 Burley bikes with midforks I believe, some of the Koga Miyatas, the Cannondale tourers (do they have midfork eyelets? I've not looked) There's a Fuji tourer (may be discontinued as per above) The Jamis touring bike.

I might have missed a couple of american market touring bikes, but i don't think so.

then you get into frames. The LHT frame. I'm not sure if Gunnar puts eyelets on any framesets.

Then you've got all the British, overseas, custom and semi custom options, and also swapping out a fork with midforks on an sprightlier bike.

I think you're interested in a full bore, long chainstayed touring bike with front rack midforks, and are asking if this traditional touring bike will hold you back while unloaded, and my opinion is NO.

Ride,ride like the wind!
