I wasn't a fan of the GT. If you want twin get the DH2. I not, Berzerker is fanstastic.
Haven't ridden the TFA, but the DOA was a fun freestyley all mountain ride. Definitely enjoyable.
Slayblade is good.
I'd also look into the Flow Drifter. Great price and tons of tech. Great ride.
Go ahead, drink that kool-aid.
