Our DVD was great- If you either go at the front or at the back (not the middle) you will get on for longer. We went at the back and spaced out by about 30 metres or so- Camera man then had us on for that 30 metres each time- about 10 times in total-BISH BASH WALLOP what a result. Folk in middle bunched together had minimal time on.Ski instructor was a babe so she was filmed a bit too and folk at front of group also got on for a fair bit due to this!
