They even make DUAL sided combinations with clips and platforms on BOTH sides like these: Shimano PD-M424

YES, there is a lot to be said about getting hooked up on your pedals when baling to stop suddenly but there are distinct advantages. More power to your pedals for one thing - and not as MUCH gain as you think, I would guess you get maybe 10% tops more effort into each stroke than without clips. Proper foot placement is my reason, i have a bit of neuropathy in my feet and find that if I ride without clippless my feet are all over the place, sliding off, pedaling with my heel or instep. Let alone getting my feet bounced off the pedals over a rough patch. For me it is generally SAFER to ride clipless.
