HELICOPTER LOTTY (1) is down a grade after finishing fourth two starts back at this track then was again out of the placings at her latest appearance in an A3 at this track over 450m (27.78). Key chance this easier class. Go well. NOIRS PRIMROSE (6) hasn't been far away here at the last two, finding the frame both times, most recently when third beaten 5 lengths (28.08). Nicely placed to grab a well-deserved win. DRISH RIVER (3) hit the frame with a second two runs back then claimed an A5 by 1.5 lengths at this track over 450m (27.92) last time. Goes up a notch but will give backers a sight. COOLABOOLA LASS (5) has strong credentials from this draw.
