I think that max jump height thing might depend on the venue. This was a DOCNA trial (my first for them). The only 24-inch jumpers were a GDS and a GSP, but it was a small trial.

Those high, elegant jumpers make for great photos, but those leaps have a cost in terms of course time. They sure are pretty though.

On a related note, I can run my tri-pod Golden in DOCNA and NADAC with a few restrictions for safety. He's such a mellow boy though I'm not sure we'd ever finish under time.
