Keep the SB. IMO it is a better bow than either the DXT or Drenalin. It shoots better, holds steadier, more forgiving, and to my ears quieter.
Or if you must get a new bow get the new S2 or SB-XT.
X2...the shorter ATA is not going to be as forgiving as your SB. But its your $$$, so get whatever bow your comfy with.
