I have seen a family of skis designed in a couple of ways and was wondering which method gives the best results or makes the skis all ski similar.

The first method for a family of skis is to make the middle ski with the tip and tail length constant along with the width on each length and "stretch" the section in between to come up with the desired length. Assuming you would use the same formblocks, you would end up with the same tip and tail heights for each ski length. Sidecuts would vary and Mid Running Surface to Waist would scale.
Blend curves at the tip and tail would vary also. I would imagine that you could play around with the mid running surface to waist dimension to vary the length of the blend curves.

The other method I have seen is to design a ski that is in the middle of the family using a fixed width and sidecut. Then you decide if you want a certain tip and tail height with your side profile. Then you decide where you want the wide points of the ski and put in a particular length blending curve at each end of the sidecut which will determine what your widths end of being. In this case the waist would be a constant. You can change the sidecut radius to make the tip and tail widths wider or narrower. I believe that the running length is variable along with the effective edge

There is alot of variables to consider here. Which method seems to get the best results for you or do you use a different method?
