But, looking at how he stacks up to Kenny Minchey standing side by side with him, and with Pyne wearing cleats, it's obvious that his height is a bit exaggerated.
To put it this way, Minchey is listed at 6' 1.5", but looked to be 4 inches taller than Pyne (not including Minchey's massive hair), even though Pyne was in cleats and Minchey was in ordinary sneakers.
Thus, 5' 9" seems pretty accurate, although I can certainly see how it could stretch to 5' 10".
