OMFG, you could get hurt climbing?
Go to the gym for sanitized safe "climbing", you wanker. Stay off routes that are beyond your comfort level if you're worried about getting hurt.
Is it really this complicated?
Btw, I think you're trolling. And by think, I mean hope, because if you seriously want to bring someone elses route down to your level, why not just chip that upper slab so it's 5.6 and then you won't be worried 10' above a bolt.
For shame...
