I'm not sure why some posters appear to think that Hook would've been such a risk in the top 5.
He's improved every year as a reserve,
2022: 2.78 (Edinburgh)
2023: 3.71 (Edinburgh), 3.74 (Berwick)
2024: 4.19 (Plymouth)
2025: 5.61 (Workington)
He obviously improved an awful lot in 2025 putting almost 1.5 points on his average, yes that was at reserve, but so was his previous average. If he was a 4 point rider in a top 5, but dropped to reserve & scored 5.5, then I'd understand the concern more.
If Hook carries on his seasonal improvement, I'd suggest there's no reason he can't match his 2025 figure when moving into the top 5.
My other point is, if every rider was dropped once they moved up from reserve, where would the future heat leaders come from lol! Every single British heat leader must have started at reserve (plus some Aussies), I guess most improving riders move up during the season, rather than between seasons, that didn't happen for Hook cause Workington had a very solid team.
Certainly seems a big difference compared to say Luke Harrison, I don't remember any Scunthorpe fans being reluctant to sign him up as a second string even through his away average was far below his home?
