sisooktom,
Yesterday I tried on most of Aria's current line and all of Shoei's, I found that the RF-1000 was the most comfortable on my head. You should wear it for at least 15 minutes in the store if not longer. I found that the cheek pads on all the helmets pushed my lips towards the middle but I got used to it after a little while(5 minutes). If you decide to get the RF-1000 I was able to find it online for ~$310 w/ free shipping. I ordered mine last night and can't wait for my first helmet
