Although Toko is a great company, I'm not going for that. To be honest I don't know any World Cup techs, but I have a feeling they would not use that tool. Any WC techs here? I don't like the looks of the guide plate, and it may not remain accurate as it has moving parts inside I must assume. The whole thing looks a little short for my liking as well.
I'm sure it's better than nothing, but not for me!
The TOKO (wax company) web page has excellent resources as well.
I also think you may find a video or two on SWIX.
One thing you may consider for next season as we are getting near the end of things. Have the shop do a stone grind and set your side and base angles. This will give you a nice flat base and less material to remove. Then it is a maint and honing game rather than a FILING chore.
