Richard,
No doubt they are good stallions but I could not see them getting anywhere near the top 2/3 because BD, AM etc are in the legend status and they get full books. McArdle and WT do pretty good but not compared to the others. I am aware that WT missed 5 seasons-Can he get that back? Their success is also based around NZ mares as well this makes a huge difference
How do Western Terror and McArdle go with 2/3 year olds in Australia? How do they rate with the newer stallions and the older ones? we know their older horses are good. I am sure they are not in the top twenty this season and last season so that really curtails their chances of getting into the upper echelon.
Breeding to race depends on cost, mare and stallion location and past performance- so those things have to be weighed up before choosing the stallion. Both of those stallions have produced about 5 good winners from mares I have in Safely Kept/Armbro operative and Presidential Ball so therefore I would be hoping for a fluke.
cheers
