I started riding road bikes with a background in BMX bikes, thus, i have very good control of my bike
My clipless pedals are the 105 spec. shimanos (SP-D pedals)

I have never fallen *KNOCK ON WOOD*, nor do i now have any real problems clipping in, the odd time my pedals upside down, but that happens to everyone that i know.
Have i tripped over myself clipping out? Heh.. yeah, but always have caught my balance.
