I have a Dagger Summit climber, its the open-face model for bowhunting. I owned the Viper until, like PY Antlers stated, I hit the front bar with the lower limb of my bow. With that being said, the Dagger is no bigger than the Viper & is much smaller than the Titan & being as the Titan also has the closed front, you might likely have the same problem that we've had. Though Im not as big of a guy as you, if I were Id go with the Lone Wolf WIDE Sit n Climb simply because its open-faced.
If its made by Summit or Lone Wolf, you wont be disappointed.
Good luck with your purchase & enjoy.
