Luckyboy,

In relation to that jockey replacement factor, it works a treat with Greg Ryan around the provincials. I have been researching this approach for a while and I believe there may be the makings of a system there, concentrating solely on G M Ryan's mounts. The only draw-back is that rank and file punters follow him religiously and sometimes value is hard to get but it provides an excellent strike-rate.

Cheers.
