Greyhound racing????

Anybody bother with the greyhounds? I had looked at it in the past but found the dividends too low to work within my system and I really didnt like how often collisions  impacted on races.
However I have found the local greyhound associations website with results for the last couple of years and  they include the odds for the races. Im currently popping all this info into my spread sheet tester and it appears  doing quinellas for the two top favs within my system might work quite well. We shall see....
