as you say wes - "If you can handle the risk"

to make such a scheme worthwhile would require each selection to be layed for reasonable amount & as we all know, that inevitable day where a couple of roughies get up within the space of a few races is potentially just around the corner, so deep pockets required.

thanks for putting the ideas out there, i have a reasonable large database containing betfair staring prices now so will have a play around when time permits & report back any findings that may be of interest.
