My major concern is horses falling, but my selection having little chance in this type of race would more or less eliminate most of the donkeys from winning. And with a minimum of 9 starters it would not be expected for all, or most, of the better runners falling or being incovenienced.

Bhagwan, that's true but in the same way the chance of them winning the race is greater than the bigger outsiders. I suppose its a double edged sword, and I would prefer to win less than lose more overall. One of the main posters on this forum researched staking plans for lay betting and said betting in units outperformed other plans. I also have looked at this with some of my lay methods and have come to the same conclusion.

Hopefully the good luck will continue.
