Are you liking the Magne-traction on the Angus? I've been eyeing up a Rossignol Experience and I've read some comments that the MT is too "catchy."
And hows the damping in our heavy, wet crud?
Are those RC boards that have the MTX that are "catchy"? Because when I heard of that I was thinking it may (or also) have to do with the RC. Becauce RC initiates into turns faster so if you're not used to it, you'd be expecting a "delay", but then it "hooks" you. I found this is prevalent when doing cross under turns in packed.
But also, many different RC shapes are out there now so it would depend on the board I guess.
Maybe what you can do is detune the tip and tail extending a little past the first seration in the MTX board. This way the "second seration" is the one that would be "hookey" if anything and by that time you would have been deeper into your turn. Pretty much similar to how a non-MTX detuned edge would behave.
But if you implement this tune, of course it might not be as overall grippy on ice. Just like with a regular camber board, you would loose that bite at the curved tip-to-sidecut-transition. Though with MTX, you would theoretically have 5 more (instead of 7) so it's not that big of a tradeoff. And with a BTX, the board should take advantage of this because as they say "it rides more between the bindings than out towards the ends like camber"....hence the "skateboard feel" (well not exactly, imo, but I guess more skateboardy than camber a bit).
But the overall effect of RC anyway is that it "spins" more easily so whether on ice or powder, you will have to get used to the different fore-aft balance because it just wants to spin. Which is also why it's easier for beginners because it "helps" initiate turns. With that said, on steep ice, you need to be more aware of edging more towards the middle than rely on the tip and tail of a cambered board holding your weight...hence it will "feel shorter".
Personally, I found that MTX grips real well on ice and at slower speeds, you can carve on it like an ice skate pretty easily. But on hard pack carving, you feel the serations vibrating your board, thought it still holds well.
