100+ days on snow race training per season. You are welcome to ride mine anytime and I'll be selling some of above quite soon.
There's no point to continue, since the discussion leads to nowhere... however I must agree to one of your points, as you see I can do some comparison myself and you were right the weight is not consistent. There are tiny differences noticeable, however this is wood core component, which was pointed already by someone and not 0,1mm difference in titanium layer thickness.
Also looking at glacier training camps of many european national teams, you'd see the SG boards Pro Team vs. Full Race are being used nearly random which believe me would have never happen if there was any construction difference, that includes Austrians, Germans... Fly over to Europe May-July and you'll see it yourself.
And last, would you be so kind to describe the riding performance differences, that you had experienced? You're talking about those, but never described so far.
This would be beneficial to lots of SG users.
