First off, Lib Tech's Skate Banana is definitely not over-hyped garbage. If it was than it would have fallen by the wayside. Instead we see several companies including K2 and DC releasing similar technologies.
ianbass, between the Seeker and the Anthem I would say go with the Seeker. It's pretty much for exactly the type of riding you describe and sounds to stiff to be much use on rails.
In terms of any other boards available, I would say take a look at the Lib Tech and GNU line. One thing that will definitely help you in your quest for turns and air is magnetraction.
All Lib Tech and GNU boards this year feature magnetraction, as well as the option of Banana Technology. The reverse camber does not sacrifice the pop and performance of the board on jumps and pipe, but it will take a bit of getting used to.
Again Banana Technology is optional on all Lib Tech and GNU boards except for the Skate Banana, which is probably a bit to soft for your needs anyway.
I would head to Lib Tech's website
and read up on what they offer.
