I reached 57 MPH on my Pantera and it held amazing on that ice coast solid crap. Wasn't the LX model though, just the regular one.
If you're looking for solid carves and crazy speed rushes - this one will do great.
Both boards will I'm sure.
I have the 2009 one and the topsheet chips real easy though, dunno if they've improved that over time.
Go with the cheapest one.
