cannot imagine why anyone in their right mind would be against ets, other than they simply don't want to change.
I'm recently coming back into the sport and am looking forward to using ets rather than chasing around after a bird knackered after a hard race to enable a quick strike of the clock.
plus I work away from home so this will enable my wife to time in the returns from a race , she's okay with feeding and exercising the birds but thats about as much a she will do , so it'll more or less double my races
