How about some background beta: where, established crack?
I have seen very few truly reto bolted cracks, if so I would chop it my self.
If you chop, do it right and do it clean or you will be no better than the retrobolter.
Don't forget a chicken bolt is just as needed on a unprotectable 5.8 as a 5.11 /5.12 test peice it all depends on whos route it is and your comfort level.

It is not a crack. It is a face climb. I am unsure as to if the rumers are true, but I have heard that Hydrotube at Flagstone has had bolts added over the off season. It was a spicey slab climb, and I looked forword to testing myself on it. Again, I am unsure as to weather this is true. I am heading on Sunday and will take a look and report back. Here is my deal. There are quite a few climbs at flagstone. It is realy a beautiful place. I have met the Fralick brothers who did alot of the route setting out there. They did so with vission, and forsight. The climbs (although I am not good enough to climb most of them) are well thought out and asthetic in my never humble oppinion. To add bolts to a well established route that is a wonderful example of what slab climbing should be, well I think that is yucky. In the guide book it sugests a #2 friend to protect the run out bottom. That is enough info. Climbing is hard. It is suposed to be hard, challenging, even life thretening.
again, this could alll be rumer, I will let you know... sorry for the rant
