Hovis,
I've got a Viper GT mate, I love it. I've got a small head and got a small (obviously!) and it's now properly broken in and very comfortable. Not particularly quiet (not as quiet as my old shark and that was slightly big) but I always wear ear plugs anyway.
Vents are very good, and I feel very secure in it. And it looks cool as feck.
You can get any design on
www.gearchangeonline.co.uk for £279.99. They were really good, rang me to check it was me that ordered it and not a fraud and it arrived 48 hours later.
Cheers,
Matt
