i set up my clipless on the loosest setting and have never had an issue on both exiting the pedals off of a skinny or staying clipped in the rough sections.
with all the crashes i have had the pedals have never been in the way, in fact after i pick myself up of the dirt the pedals have never even entered my mind as to why i bailed.
i find having the extra grip on the bike on both the way up and down is awesome.
and as always it is what you are used to, if you spend the time to get comfy with the clips, which doesn't take long, you will be happy for all the riding options.
I ride with the Shimano DX, prior i had the Shimano with out the cage.
