One more tip.

1. Top CP rating
2. Top Don Scott Final Rating
3. Barrier 5 or wider
4. ?????

Add 1 more filter (and if you read my posts you will know the filters I usually apply) and you get a unitab figure profit of 17% and a betfair profit of 30%.

Or alternatively do this filter:

1. Top CP rating
2. Top Don Scott Final Rating
3. Barrier 5 or wider
4. ?????

and you get 15% unitab profit and a 22% betfair profit.

Add both those filters and you get a 41% unitab profit and a 46% betfair profit. Selections is down to 317 though.

Now you need to do your own research and work out what the 2 filters are.
