KNOCKDUFF MARKLE (2) missed the frame last time but just three runs back was a strong D4 winner (17.34) at this track over 275m. Better than last run and makes appeal this time. SKIRK MIA (6) drew this same trap last time when in the minors (17.47) in a D3 over 275m at this track. Must include in calculations. ACTIVE HILL (5) doesn't have the best strike-rate. Finished in the minors latest when third (17.54) at this track and may be close to breaking through. Form at the trip sound including two wins. Bold showing expected. LINKS BATMAN (4) is in the mix despite missing out at this track last time.
