To suggest rapping after pitch two is to suggest not doing the route. After all, you'll never know what you're worth if you bail before the route's finished. Remember: groveling builds character... it gets you up stuff.
It also helps for all those 50 Classic Climbs....

Don't be a quitter! Chimneys are fun!

Don't bail, the third pitch is great!

Seriously!! How could anyone suggest bailing after the 2nd pitch? The 3rd pitch is the easiest of the whole climb!!

Echoing the three before: Do it to the top. The third pitch is good fun.
