One thing to remember is that a comp, any comp, only takes a percentage of the recoil out. Adding more power will increase the recoil, even if the comp/brake becomes more effective at the higher power factor. IMO the best way to achieve both goals is to load the lightest projectile you can find, with a slower powder, and aim for the usual 130pf with that. It will produce more gas to operate the comp more efficiently without creating additional recoil for the comp to have to offset.
