This has little to do with the boot board and more to do with boot design. Langes are usually very laterally stiff - known for it actually - especially the current generation. Technicas may appear to be laterally stiff, but the direction that the leg tracks when flexing them is commonly inside, which de-edges the ski.

Oh boy! Wish you hadn't told me that.  Makes me want to go boot shopping again.   

Actually, not really, as I rather like the Tecnicas for other reasons.  Although I do miss the fantastic edge grip that my Langes gave me, the Tecnicas are better in several other respects, that overall I'm much happier in those.  Cuff fit, alignment (perfect right out of the box), progressive smooth flex, longer flex range. and a few other things, are all better in the Tecnicas.  At some point I would like to try the new Lange RS/RX series, as they look like a vast improvement over the ones I had, but for now I'm content.  But....just out of curiosity, I will check the alignment and see if the tracking changes as I flex forward.  You've got me intrigued now.... 

Correction to my first post:  I had the Lange Comp Pro, 120 flex; not the Super Comp, which had a 140 flex.
