I don't believe the few m calculated shorter turn radius for the 188cm FT62 over the 196cm makes a practical difference, the shorter edge and less rotational inertia probably does more.
I have no difficulty maneuvering the 196 cm FT in steep terrain.
Regarding the Rabb, simple facts: it has 1-2 mm more sidecut in the front and back, and 6mm more width underfoot, so clearly a bit more designed towards turning on loose snow relative to the Falketind Xplore. On the other hand it would have a slight penalty in XC performance but probably not so much. @telemarius did a nice comparison some time ago.
On hardpack downhill i think the benefit is probably there but not very noticeable.
One "downside" with the FTX is the white base. It's harder to see the condition of remaining grip wax on the base. i think the Otto and Combat Nato have most practical bases for grip waxing, in black.
I got my Falketind X from the shop new mounted with Xplore bindings for 370 $ US which was a killer deal i couldn't pass over.
The cheapest Rabb with bindings would have been 50% more expensive for me to get.
Bottom line the extra cost wasn't worth it for me and my practical use and i pulled the trigger on a killer deal for the FTX. I think the FTX is much closer to the Rabb than the Ingstad. At equal cost i would have gotten the Rabb.
Here is that other thread again comparing Rabb and FTX

I am a bit surprised that telemarius thinks the Rabb is maybe on the wide side for the Alfa Free, considering the width difference is only 10%, but perhaps he drives the skis much harder than me with his background in high level XC.
