I’ve just tried putting in your parameters for Trainer Stats and only came up with S Bin Suroor.
If I clicked any race instead of just Handicaps,I got Suroor,Fanshawe and Beckett,so I’m not sure what is going on there.
As for posts on here,it seems like a bit of a closed shop,perhaps subscribers are not keen to share their experiences.
I know I put a post up a good few weeks ago and didn’t get any kind of response,so I don’t bother anymore.
Best of luck with your selections today (listed above) I’ll be following them with great interest.
