Thankyou so much for your help guys . I like the two toned coloured ones too and although the white is nice I think having a light silver on top would look that little bit nicer and still be nice and cool. Just like yours Kiwigirl, maybe even a shade lighter if they have it! Even if the darker shades don't heat up inside I think I still prefer to stay as light as possible considering how much hotter it gets out here and the long float trips. How are you liking your Imperials?
