Thanks Dave, that is good information.

I tend to play quite a lot of longer priced horses and like to employ the exacta as a place bet strategy. I will generally wheel these horses front and back with the two betting favorites in the race in the exacta. So being able to potentially eliminate some of these low priced horses from the bottom of the exacta would be advantageous.

Dave: I assume that your research is for cases where low odds horses can be tossed from win consideration. Has your research also come across situations where the low odds horse or horses can be tossed from the place hole as well?

I happened to notice that second positive work that you mentioned after I made my initial post. There just seems to be something about that second Lasix angle that makes it a very potent catalyst when combined with virtually any other positive change.

Not currently a Determinator user and this is not meant to be a redboard, but I had this horse as a play because I just love 2nd time Lasix horses combined with any type of potentially positive change: In this case the improved workout since last raced and blinkers-on. I have had more than just a few scores lately in maiden races that look very similar to this one.

In situations such as this I almost always will go with the higher odds horse, even though that would tend to fly in the face of general win probability. You need to separate yourself from the crowd in contests and that almost always means going for longer prices.
