Surely it's about finding a balance. Realistically what full time club would Kane be guaranteed the same game time as he would at Dumbo (Morton and the Pars aside as that's a step backwards).
Falkirk, Livi, Raith and Queens. There's cases for all of them to leave him out. Game time is the malt important thing for a lad at his age and he will be playing against some very good players this season. Experience he would never get at youth level. He will get some new coaching for the Dumbo guys while retaining the core training with his parent club who will not neglect him as they obviously see him an asset. They could get £500k+ for him if he develops like May so why they definitely won't neglect him.
