I have a regular .25 Condor w/24" barrel and "barrel shroud," so very similar to your setup. I've installed both the adjustable top hat and trigger mod from TalonTunes and it makes a world of difference. The top hat can conserve a lot of air with a restrictor or go wide open and make a lot of power. It throws Eun Jin heavies supersonic with ease and needed to be tuned down. It's now set to launch JSB jumbo kings at ~1,050 fps.
