I've got the Dinottes and ended up putting the 3w spot and the 5w flood on the bars. It is much more convenient than the helmet mount and seems to light up the road better. The AA batteries go on the stem.
I definitely agree with the high marks for service, too. Very responsive, and they added a bunch of little extras (o-rings, straps, etc). that make mounting more flexible. The only regret I have is not waiting for the 10w light!
