Pretty much it's established that the longballer's gun of choice is either the Shocker, sub 250 psi Cocker, Impulse, tweaked Matrix, or Adrenalin Angel. Proper bore to paint match is extra crucial here, but rather than going with a Freak I would say if you really want the absolute best, only matched straight bore barrels will do, such as the DYE SS or Custom Products bored to different sizes. In my opinion 14 or 16" barrel length is a must here. Freaks and CP pro will work well, but the exta 1-5% lies with 8-9 straight bore inches rather than just 5. However, should you not be able to afford or don't want to spend the time with that, 5-6 inches that do match is always better than 14 inches that don't.
