Bull,
It seems that almost no one uses the hinge connection for the K3 except Amazon. I wish I knew why.
While I am happy with my LIGHTED Amazon cover, I also think that a few of the edge attachment systems referenced earlier in this thread would be good alternative to the hinge system or the (IMHO) awful straps.
