OBSIDIAN (1) Good win by 2 1/2L last start around here and honest performer putting a tidy record together. Form has been improving over recent runs. Massive hope. SAIL THE SKY (8) Racing on a quick back up. Below par performance when 6th last run here but gets a favourable gate. Likely to be well placed early. Rising in weight. Goes close. UNSOLVED RIDDLE (5) Back from a break. Finished 6th last time at Kenilworth but gets a reduction in weight. Coming to a new trainer. Likely to settle back in the field. Will be around the mark at odds. GUERILLA WARFARE (3) Performed below standard when 6th last time at Vaal and hoping that the added weight won't hurt. Will be pushing for a forward position early. Chance in this field so include in exotics.
