4.50 Sir Gregory 15/2 2PL seems to prefer the Polytrack surface.
6.30 Louis Treize 7/1 2PL may prefer a longer distance.
8.20 The Thin Blue Line 4/1 2PL may not be up to winning a class 3 race.
8.30 Bossipop 4/1 2PL may need further to show its best and this race might not be run to suit it.
Good luck if you follow.
