Yeah, being clipped in is generally far more secure to me. I know that if I am curb or log hopping, I would much, much, much rather be clipped in. I started learning to bunny hop on flat pedals (because I started mountain biking on flat pedals), but I can't do that at all anymore.

I would also suggest that stopping hard can be safer clipped in because you can keep your weight back *without* risking feet coming off the pedals. I have gone over the bars and taken the bike with me, but many more times I have stopped hard enough to lift the rear wheel off the ground without going over the bars.

But agree with the "whatever makes you feel safer" advice.

I do prefer flat pedals (or not clipping in to my SPDs) for (1) practicing wheelies (I have not mastered this at all!) and (2) unicycle.
