Kev,

I think that very very very few people have been "hitting it hard for years". There was a window in the 70's and maybe early 80's where information like speed figures was limited to a few people and there were great opportunities. But in the "information age" we are in now, it is very tough. I am sure some do it. But very few. And those that do "hit it hard" have the discipline to limit their plays to very strong opinions. They may bet 1 or 2 races a card. No more.
