3.30 Khurombi 2PL seems better on the Tapeta surface and may need further to show its best form.
4.55 Astapor 2PL needs to improve time wise to win this race and a longer distance might show it in a better light.
5.20 Bernard Speirpoint 2PL has only produced slow times on grass and a longer trip might suit it better.
6.50 Treacherous 2PL hasn't won over today's distance mainly because it seems to short for it.
Good luck if you follow.
