I use the mag 9. Finally a lid that fits my big forehead. I always got a sore forehead with any other helmet I used. The flip down tinted visor works well for me. Clears my eye galasses easily. As previously stated. The Jand M headsets to fit due to the thickness of the speaker. I have found with the clear shield up all the way it touches the visor on top of the helmet and has caused 2 wear mark on the shield from the contact. Other than that very pleased with fit.
