There is too much of a disparity in HL strengths..
Within the 21 HL's there is simply to much of a gap...
Cook was a decent No4 for the Aces and is now a No1...
Tungate is (at best), a No3, (and only at certain tracks), yet rides at No1....
Ipswich have such a strong team because they have used the UK reduction brilliantly well, but also, more importantly, they have every rider in their team in precisely the correct position to match their capability in a league with top level world stars...
Not many teams have ever had that to work with over the years, therefore, no surprise they are hammering teams, as "head to head" v their opponents, from one to seven, they have the better rider..
Seven teams of seven riders has meant too many second strings having to ride as HL's for the league to be competitive...
