I use a DefNder as well. I don't have the same problem that jimbo has though. Mine is comfortable, and don't even notice it. It has the bars on the side that protect you from side impacts, which the HANS does not. Also, the DefNder has adjustable angles if you ever want to get into a different type of car. Ex: I used my defNder switch from my FV to my ITA Civic, HANS users would just have to buy a whole new system. Good luck, IT racing is fun!
