Pedals for track

There's a thread for that:

But obviously Hippy is at least half right. If you already use SPD-SL on the road or have no prior affiliation, SPD-SL is the right clipless pedal for track use. If you already use Look Keo on the road and want to use the same shoes, Keo is fine for track use too.

I did utfs but missed that, cheers Tester.
There is an offer on look keo max carbons for £68 on so good discount from £140. I've no leaning between keo or spd-sl but seems the forum has a preference for shimano.
