If you're spending hundreds on building a rocket, going cheap on the harnesses may be the last mistake you'll make on that rocket. Teddy's the best when it comes to making harnesses that are high quality, dependable, and long lasting. Don't trust your big projects to anything else.
Video is my 6" X-15 L3 cert using his harness. On the second flight, the rocket failed to separate at apogee, csme screaming down (whistling) and main deployed. His harness held up and very minimal damage to the rocket! Amazing.
