Tim Burke hitting a medium drive during a practice session.
In the 2013 ReMax World Long Drive Championship, Tim Burke reached 427 yards, so we know he is able to hit it a long way, have a look at his medium numbers from a practice session back in august 2016.

Unorthodox backswing then has a great look half way into downswing with his body stable .
Hogan-esque. Nice lag.
