Frogs are super easy, are you sure it's the getting clipped in part that's a problem, or just the getting started? Try pointing the bike across the road (obviously, when there is no traffic) and getting started at a less steep angle, then turn and steer back to the right side. You can pedal on Frogs OK without being clipped in, too - get a little speed up then get clipped in.

Power strips look like they are harder to get in and out of, i've never used them but my tour partner did. looked hard to me.
