Jesus H. Christ. That sounds terrifying. I don't think we've a weight limit but that's definitely something i might suggest to one of the staff I hang out with, she'd probably relay the info back to the boss. It;s a really good idea (if enforced). I do more bouldering than sport climbing, so it's quite frequent some of the more hample beings there opt to jump down from the top and nearly wipe people out. It's exceptionally frustrating, especially as they jump away from the wall and towards climbers.
