Interesting sportshog your data base for trotters would be a good tool.

I believe all the info is out there (as Crash has said) but you need to find your niche and concentrate on that, this is where the data base would come in.

My data base is sourced from three free web sites (manually), the selections from one, form from another and the odds from another. The selections by themselves brake even at Tab odds, this is where the form comes into it. The data base will give me three sets of ratings from which my bets are selected.

Cheers and good luck with it
