Took the plunge this week and got myself a Bell Bullitt.

Tried a few on and and found that I was most comfortable in the large but there wasn't a lot of difference between it and the M and XL.                                                                                          

The inside padding looks plush at first but is really bare minimum just like the 500, but is a much better fit  for my head shape.

The field of vision is unreal and almost as good as a 3/4, unlike any other full I've worn.

The only downside is the noise, it's as noisy as my 3/4 bell and probably a bit pricey for what it is.

 

Just a quick update.
Be careful with the visor when you first get the helmet. Mine had some kind of grit or Perspex swarf on it straight out of the box and it scratched the helmet above the face opening and the chrome trim.
Before opening the visor, remove it and check that both the visor and helmet are clean and free of grit.
Did a couple o hundred K over the weekend with two hours of crazy head wind and was more than glad i was wearing it. The helmet has settled in great and I'm happy with the purchase.

how are you finding the noise and airflow?

Hey Stel. The noise level is similar to my Bell 500, maybe a tad quieter. I will do a back to back test between the two on the weekend. There is a whistle when the visor is up and you are doing above 40K but its really not that bad. 

I ride wit ear plugs anyway.

The air flow is pretty good but I don't think the chin vent switch does anything. The air flow seemed to be the same in both positions.
I'm keen to try it with no sheild and just some sunnies.
The field of vision really is great a d in the end that's what sold me.

Too bad the Biltwell version isnt available here. Half the price.
