Maybe I missed it, but for me, it's all about the cleat, not the pedal. Shimano makes the best multi-release cleat. See link (The SPD SH56 I think? )
(You need to Login or Register to view media files and links) Ultimately, I prefer to ride clipped in. Its a no brainer when riding at all our local tracks where you know where everything is. I know when to get on the gas in advance of the obstacle so i don't lose momentum. That's when most newb clipped crashes happen. You lose all momentum and even though you try, you can't unclip and over/down you go.
But with the easy out cleats, and my pedal spring tension set on easy, I am relatively comfortable riding anywhere clipped in because I know i can jerk my foot up at anytime and the shoe will release from the pedal. Some people would hate that, but i love it. I still feel connected to the bike and i can crank/pull up with my foot when I need extra power and it stays clipped in.
I believe that when riding clipped, when you approach a difficult area, or tough climb, or similar you have to either decide to hit and go all in for it and keep the rpm's up and don't stall, or unclip/prep to unclip and hike around the obstacle.
BTW, if you are just riding mostly flat stuff, then going clipless is a no brianer.....do it.
A few tips for beginning clipee's, wear a combination knee and shin guard. Find some bike shorts with hip pads. Add in some slim elbow pads and/or arm sleeve if you can.
My newb falling over clipped story. I was flying downhill towards the creek where the steep ramoed bridge is at Ann Springs Greenway. This was like 8 years ago. The bridge has a short but steep, like 4 feet ramp to get up on it. I hit that ramp, however I was in a TALL gear and I lost all momentum. I went down left. Hard. My head hit the rail, as me and my body went through/under it. my hip hit the edge of the ramp, i flipped upside down, and my bike got stuck on the rail and I was dangling under it. All in all it wasn't that bad, but everytime i see that bridge (which now has a different railing system) i can assure you i am in the right gear and I have plenty of momentum....you live, you learn. I also fell due to being clipped in the rock garden not far from said Bridge.... All of this happened using the standard cleats, not the multi-release clips.
So I say get the clipless pedals. Something cool. Also, the clilp-less shoes are way better than flats. They look the part as well.
