does anybody out there have different models of Arai's and can you shed some light on how each model differs from each other? i tried them all on and they all feel the same. i'm guessing the only difference is the airflow??
i currently have the quantum s from about 10 yrs ago. i think i'm due for a new lid.

) and get the other and try it for a couple. 
too bad i did not do my homework before going there so i can mentally take note of the different shapes that arai has to offer. ultimately i did narrow my search back down to an arai. all the others just didn't feel right. now i just want to narrow the models down. i didnt feel much difference in each arai so now i am trying to justify paying top dollar for the RX7 corsair or not. i think i am leaning towards the new vector.
