I actually live in Scotland and never used them there.... use race skis or Kung Fujas here...
So far the Kartels have been to -
Val D'Isere, France, Skied all 6 days there on them with everything from ice to 6 inches fresh...
Whistler, Canada - skied 3 of the 6 days on these there... the 3 snow days I used the Billy Goats, the other 3 days I loved the Kartels just cruising about all over the mountain...
AltaBird, PCMR, Brighton, Utah - well skied 10 days there, think I only used my billy goats 3 days, 21 inch Sunday at Alta was epic. The kartels were perfect for spring conditions in Utah, didn't complain once except one run at PCMR where it was 9am sheet ice... great fun skis. I used them one day with a. few inches fresh and no complaint at all but had the BG in the car for the deeper days....
This year I have booked Val D'Isere again for New Years week and only plan on taking my Kartels...
Will go some where mid February and take both BG and Kartels and same again for SLC in early April....
did that help??? just rambling....
