@tomahawkins, I've looked at the 23-24 catalog you posted upstream. TC-SU is your ski. TC means tech comp- S ='s short turn. What's the U and now they have B? Any insight? Also, what's the KEOS models ?
Yes, the U is last year's, B is this season. Not sure what the lettering signifies, but it's the same ski with a slight construction change.
The Keo's are technical, all-mountain skis, but their definition of "all-mountain" is somewhat different than here in North America. I've only skied the KS-XX in the line and for only one day so far, but it's very demanding. Mine is 172, 69mm underfoot, an 18m sidecut, with a slightly softer mid section than the TC-SU, but it's still stiffer than all my other skis. Though it is my understanding that the whole Keo line varies quite a bit from model to model.
If you were to choose either the TC-** or the KS-XX, be prepared for possibly a lengthy acquaintance period. At least for me, they are unlike anything I've skied before.
Really looking forward to
@Mike King 's commentary on the TC-MT throughout the season.
