fair enough, and to be honest he has beena decent hight for me since he was a yearlingEssentially who knows. You can string test or look into lineage, but my last boys parents were 16hh & 16.3hh and he was 19hh with shoes on, so it's how long is a piece of string.
If 14hh is big enough for you, then I wouldn't worry about it as anything will be a bonus, and nothing won't matter.
