Best handicapping angles

[MISTERGEE]

I like "hidden" changes with lasix or blinker change
let me try to explain, this is not first time lasix or change of blinkers
but first time to new surface or distance with the change
an example, say a horse has been sprinting all along then gets lasix or blinker change in one of his races sprinting, now he switches surface or distance, this is when you bet, it will not show as first time lasix or blinkers but it will be his first time trying new surface or distance with that change even if he has tried them in the past without. confusing-maybe but worth it as an angle-
