Ambiguous statement for me regarding coming away as better riders. Perhaps you could define what you mean by better riders ?. Young riders as we seen with Max Perry get dropped if not performing he certainly didn't come away as a better rider. Vinnie showed rapid improvement in his form than he had showed in the NDL the season before.
Poole tend generally to make good decisions on rider recruitment ie good eye for improvers. Such riders would become more experienced and improve wherever they ride imo.
