I totally disagree on the squirelly traits of the Magic. I own one and find it a very damp, stable and confidence inspiring board when ridden on hardpack at speed.
Does the Magic have some traits that are great for groomers/hardpack? Absolutely - specifically dampness and edge hold.
Is stability and lack of twitchy-ness one of these traits? No way.
Your prerogative to disagree with me on this. I read your initial review and happy to hear that the Magic is working for you - I also think that it is an amazing board. But I stand by my opinion on suitability for groomers (which BTW is also Lib-Tech's official line).
Buttering and any kind of park other than the pipe are also not strong suits of the Magic.
