Radek, When we did this a few years ago, we were able to rap off the other side of the Stripe Rock a single rap and a bit of down climbing. I'll ask Tim if he remembers the exact distance. Just a handy FYI
I just did this route last weekend. There is a two rope rap on the opposite side. You just have to walk left of the top anchors to the other side of stripe rock. Then head down a ramp slanting to the right. At the end of the ramp you will find a two rap ring anchor.
