Base Grind.. structure selection..

post #1 of 4
Thread Starter 

Typically I take my skis in when needed for a base grind - start of the season is just around the corner (for me) and in they go after a few years of just regular maintenance. The shop has a wintersteiger and the tech asked me what type of structure I wanted. I guess the machines these days have the ability to make all sorts of patterns - my old skis (which are the one to be ground) are a pair of Dynastar Speed Couse Ti - if I look closely fine linear structure (tip to tail) - BUT if I look at my new skis (Head iRace) they have a angular crossed structure. 

So if I look at the Wintersteiger web site there is a picture of different structures - angular crossed, arrow, wave and more..  why all the choices? And when asked what structure (pattern) does it make much of a difference?

 

Cheers

I've become a real fanboy for chevron (arrow) grinds because they are (a lot!)  faster than my old light cross in sloppy snow without sucking too bad in fine new snow.

3 pairs have the KT4 grind described here:

The old Racetigers have the Swix 7 grind,

The Volant Chubbs have a coarse linear and everything else including pow skis has fine linear.

It mainly depends on what the shop's machine can do, and how well the tech that does your skis is trained, as well as the shop's desire to cut the new structure pattern into one of the stones used on their machine.
