Yeah Dumarton are probably, by far, the best option. As he'll start the season as first choice, while other clubs in the division may not. I'm not meaning we'd shun him completely, but I feel like there might be less focus on him due to the fact he can't actually play in games for us, if that makes sense at all.
Yeah theres obviously positives, and I've admitted I might be wrong, but it would maybe have benefited him to be somewhere else, and be away from us for a while, simply so he can get away from being the "rookie" and build his ego being a key part of team for a year or six months, instead he'll be back at us a few days every week and back into this "rookie" mindset. May got around this by being massively self assured, I'm not sure Kane has the same arrogance yet.
