I've tested a couple of flip-ups including the Multitec and came away unimpressed with all of them. They are heavier, usually don't provide as much peripheral vision, and I'm just not as confident in a flip up helmet in a getoff. I'm also a huge fan of Shoei, own both a black and a white RF-1000, and won't consider other brands at this point. But with the current offerings, I won't be looking for a flip up when it's time to replace a lid.
