Honestly, since you are new to the 2011 platform I would just try to find a used edge or eagle to get acclimate the to platform. All the while trying out the short/long, polymer/metal, non/lightened. Even going from a 10 to a 12.5 lb recoil spring changes how the gun feels and shoots. First you need to decide what kind of shooter you are? Can you handle heavy recoil, how fast are you transitions, what kind of impulse do you like? A light gun is harder to control but will move faster. An all steel heavyweight is a tank but recoils like a pussycat. All things that are considerations.
