I put the Binder Design "Spike" through its paces on Sunday at the Tripoli Rocketry Association Australia launch.

Flying on an Aerotech G71R, the boost was very fast (thus resulting in me not getting more than a smoke-trail) and dead-straight with no obvious rotation, the two 18" parachutes popped out right on apogee (10 second delay selected) at about 2200 feet (as estimated using RockSim).

The spike came down without a scratch less than 100m from the launch pad. A perfect flight from what has proven itself to be a fantastic kit. Oh, and this was my first G powered flight!! Amazing stuff :)
