From reading that, it looks like the CNC ported version of the stealths may be pretty good, BUT, In comparison with the trickflows, how do they compare on a performance level? Do the Trickflows still outflow the ported version of the stealths?

The Trick Flows are most likely still better. Not sure 440 Source still offers that CNC version.
