Well today was the day - had the opportunity to go and try a few helmets.
Looked at some LS2 modulars, plus a few others, but none the right size and my current LS2 presses against my forehead and is uncomfortable after a while.
Moved on to Motoadelaide, they had the Nolan N1005, which was a good price with good reviews. However, it pressed on the same part of my forehead as the LS2.
Even though it was outside the budget I'd set myself, I tried the Shoei Neotec II.
End result - perfect fit, which will do for longer rides, no pressure points, good fit all round. I think the extra $ will reward me with overall comfort & quality.
My Aldi Bluetooth has even fitted on - with a minimum amount of work.
Now to road test it.
