Many thanks for your input. The videos are very informative and I think I may have some of the same issues you had. I actually ski telemark most of the time and have only recently bought new alpine piste skis.
How much skiing did you get prior to your L2 and between the course and re-sit?
Prior I'd skied loads, ie 20+ years but I'd done little or no training.
Between the course and the resit I did
week family skiing
long weekend with Inside Out training
Week with inside out specifically BASI training
long weekend with a few friends to a place with easy blues to practise carving
a week with the family prior to the resit
