Possibly they don't pay more per point or per mile than other clubs. But have extras like free accommodation, free workshop use and help finding sponsorship. So the cash from the promotion is the same as others, as they claim, but the overall package they organise is better.
They also don't hang about, I heard more than 6 months ago that Rushen had agreed to ride for Poole in 2026. I'm not sure how long Wessex Marine have sponsored Rushen but that is likely to play a part in where he ends up given that they also sponsor the Pirates.
