What ski size to pick

[persio35]

Hi there,

I am interested in buying D3 Helix 2014, but I can't figure out which size to buy. I am 1.75cm tall and I ride 55km/h with 16m rope. At the start of the season I weight 80kg and in mid season I weight 78kg. Should I chose 67" ski or 66" ? At the start of the season I think I should use 67" , but later in the season 66" ski size.

I would also like to know what should I look at when choosing ski size.

I know I have to look at weight and speed, but should I consider how tall I am and how long rope I use and if I start to ride faster or use shorter rope.

It's really confusing for me.

in imperial measurement

165 pounds. 5'8 " and ski at 34 mph on a 22 off line.

Seems to me you ought to try both and see what works for you as you are a bit of a in-between application.
