Ok, I've been looking at buying a new jacket and I decided on the First Gear Kilimanjaro 4.0. I love the look of the black and grey, it's got plenty of reflective material so at night it will be very noticible and I've got plenty of lights on the bike.... But...., the yellow and black is also far more noticible during the day. Which to buy? I'm making the purchase tonight so feedback is greatly appreciated. Does the bright yellow make that big a difference? Thanks....
