I have found that the Radio TAB has the highest SR amongst its Top 2, compared to any newspaper or subscription service.

Based on 21,000 races.

Its SR is ...
1st sel 26%
2nd sel 19%
3rd sel 14%

Top 2 selections = 45% SR

Most other tipping formats have that percentage SR for their Top 3.

So all you have got to do, is bet one of them that you know, is value to ability, for 4 units & bet the other one at 1 unit as a sort of Saver bet..
4 + 1

There 45% SR

The SR is 48% if you target the first 4 races only.

Your now laughing like a Hyena.
