Replying to Alpha 2 mounting?

I put this in the unworthy thread but got no answer.. so I figured making a thread wouldn't do much harm.

OK so got 09/10 Armada Alpha 2's in 182 for $299. How do they handle in the park and on groomers? Should I mount centre or like 1.5/2.5 back? I'm skiing 80% park 20% groomers. I'm 5'11, 175lbs. How short will they feel? I've heard that the Alpha 2 skis quite short due to the rocker. I just came off 167s (short, I know) and I don't know how big the difference will be.
