Another tricky contest. KAMMERZELL HOUSE (10) debuts for a leading metro yard and has been well-trialled. Went close at Tatura his latest and the in-form Duffy sticks off that. Has the blinkers applied suggesting intent. Stablemate MISS AURORA (11) has some support at Moe on debut and did little after a slow start. Maps well and the blinkers go on today. Quick improvement is likely. NAVAL OFFICER (3) was plainer second-up for the new barn but showed enough on debut to consider. The blinkers come off and fitter can improve enough to make the finish. FLUTTERBY (4) and STEREO HEART (8) are improvers who deserve consideration.
