If you find someone who is the clubs regular top runscorer/has a bit of a rep of being one, and is involved with coaching juniors, is that not the ideal mix? Regarless of level.
Kids will be attracted to both facets, while seniors will more than likely follow too (perhaps a lesser degree), provided the player talks positively about the brand.
I find there is a lot of interest surrounding smaller brands. I would coach around 100 kids (13s-17s), many of whom like to think they know it all about bats, but whenever I showed them my rk, there was a lot of interest. Same in seniors when it was lent out.
It also helps smaller brands that society as a whole likes to be different/have something new
