KCee I haven't tried the Mavrik, but I would put the KE4 up against the Rogue, Epic Flash and G400SFT. I did get to try a SIM2 Max and Epic Max on the launch monitor recently though and they were impressive. Possibly a bit more forgiving with better feel/sound. Didn't really see the yards though and obviously a much higher price point.
Good to know. I gamed the rogue for a long time and really just switched more out of boredom than anything. I liked the performance of the flash but hated the sound and feel so the switch to the mavrik was easy as I love the soft, muted feel from a driver. I only gamed the flash a couple of rounds and it seemed similar in performance to both the rogue and mavrik.
