I've let a Roof Daytona look after my bonce for a year now.
 Great fitting lid, fairly quiet, I actually like the seatbelt type fastener cos you can operate it with gloves on.  I find the visibility good.  Only criticism is visor changing - a complete faf!! just remember to keep a 2 pence in your pocket.
 I've got a silver / black one too (check out the avtar) is this the same one as you?
