Bonafide to Mantra, Anyone Done This and Care To Share Thoughts?

I have the Blizzard Bonafide (2014) and I'm thinking of switching to the Volkl Mantra. I'm obviously not going to be able to demo an all mountain ski in a single day or even trip in all the conditions those skis might be used in. I like the Bonafide but I'd like something a little less effortful to ski. Is that the Mantra and if so what are the sacrifices?

Thanks
