Here is the TTL body with a Power Team figure, G.I. Joe, an Ultimate Soldier, and a DiD body (different head). The TTL body is taller than G.I. Joe and the Ultimate Soldier, shorter than the Power Team figure, and about the same height as the DiD body.
Here is the TTL figure with my tall guys - Scottie Pippen, Triad Omega, and Darius Reid.
