i've already crashed my group buy frame twice, one time a car pulled out in front of me and i hit the bumper, the other time i clipped a mirror with my handlebar. both times i was thrown over the bars, both times the bike went flying through the air, both times it's survived with minor scuffs, despite my cuts, bruises, and minor dislocation.
getting a new frame gave me a little too much gusto. now i've calmed down a little on the street, but point is the frame has held up wonderfully.
i'd say so far my frame has experience only (semi)catastrophic successes.
