The XCD quiver of one is a ski that covers Nordic terrain efficiently and handles real mountain descents. That corner of the performance map is nearly empty. The Fischer S-Bound 98 gets closest — its Dual Skin system (fishscales + removable Easy Skin insert) makes it field-adjustable for any terrain, and the scores put it right at the edge of the balance zone. Åsnes skis take a different approach: the Rabb 68 and Ingstad trade flat efficiency for structural mountain performance, scoring one full point higher on downhill power through a sandwich laminate construction that holds edges where other touring skis wash out. The Åsnes Nansen splits the difference. Which one is right depends on what “quiver of one” means for your terrain.
The XCD dream is simple to describe: one ski that covers 20 kilometers of rolling forest road efficiently, then holds an edge on a 30-degree descent in breakable crust. No setup compromises. No hauling two pairs. Just one platform that does both.
The Telemark Talk community has been chasing this for 40 years. And the more you dig into the data, the more you understand why so few skis get close.
Every meaningful design decision in an XCD ski trades glide efficiency against downhill power. Width helps turning but generates drag on long approaches. Sidecut enables edge-set on descents but makes the ski wander on flat sections. Stiff flex holds better on icy terrain but fights your kick on rolling ground. Metal edges add security and weight you carry all day.
When you plot the Hall of Fame skis on these two axes using the actual database scores, the pattern is stark. The Karhu XCD Guide scores 9 on downhill and 1 on glide — the turning king, and a known drag across any flat approach. The Fischer Transnordic 66 flips that completely: 4 downhill, 10 glide. Both are legends on their home terrain. Neither works on the other’s.
The diagonal is real: every ski sits roughly along the line from top-left to bottom-right. The balance zone — high on both axes — is nearly empty. Getting there requires solving design problems that most manufacturers haven’t.
The Fischer S-Bound 98 is the only ski that reaches the balance zone, and it gets there two ways. The ski itself is well-designed for balance: 69mm underfoot with a Nordic rocker tip that initiates turns more easily than narrower expedition skis, while still tracking efficiently on flats. But the real mechanism is the Dual Skin system. “Dual Skin” refers to two grip modes in one ski: a wax-free crown pattern baked into the base for rolling terrain, plus a slot for Fischer’s Easy Skin insert — a kicker skin that clips in for steep climbing and pulls out for descents, adjustable in the field without tools. Fischer’s Easy Skin is consistently rated the best-engineered grip system in the category: more reliable in cold and wet conditions than Åsnes’s X-Skin, and quicker to swap. The X-Skin uses a bonded-edge attachment that excels technically but is harder to change on the go — better engineering, less practical versatility.
The Åsnes answer is structural. The Rabb 68 and Ingstad both score 8 on downhill power — one full point above the S-Bound 98 — and they get there through construction, not grip systems. The sandwich laminate on the Rabb 68 builds torsional rigidity the S-Bound can’t match: the ski holds an edge in steep, icy terrain where the S-Bound washes out. That gap matters more than one database point suggests. In breakable crust or refrozen snow, the difference between dl=7 and dl=8 is the difference between controlling a descent and surviving one. The trade-off is gl=4 on flats — slower on long approaches, but entirely skiable.
The Åsnes Nansen is a different calculation. At dl=5 and gl=7, it sits in the center of the chart — the efficiency-oriented option in the Åsnes lineup. Right for routes that cover serious distance with only moderate descents. Not the mountain-touring choice, but a genuine one-ski setup for rolling backcountry terrain.
