BMX pedals with the retrogression straps or a nice pair of hold fasts are probably the most comfortable/easiest to clip in and out (besides going clipless)

However, I really don't like the look of clunky BMX pedals on track frames, so I bought a couple pairs of Aurora straps that fit into MKS sylvans or most other standard track pedals. They feel way more secure than my original clip/one-strap set-up (maybe I'll try doubles down the road).
