The chatter isn't caused by the hollow tip necessarily. It's caused by the lack of overall damping. I also suspect excessive camber may contribute to chatter. But sounds like you got it under control.

Excessive camber definitely causes chatter, had that issue in some other builds which had more camber than planned.

Thanks for confirming excessive camber and chatter. I wasn't 100% sure but it seemed plausible that it could be the culprit. I planned on making a new bottom mold with perhaps 5mm. I noticed that FIS racing skis had minimal camber and heavy.

Yes, the "real" racing skis nowadays are hard as hell and have little camber.
I have a 193cm long Völkl GS racer as well, thats a really nice ski though its so hard and long . once its on the edge its going nowhere else. But for my racing skills 27m radius is waaay too much, so I built a ski that has the edge grip of the 193cm Völkl but has 21m radius - perfect for me :)
A bit too much camber maybe, but it will wear out when the ski is skied more :)
