I usually don't entertain this subject because I love bouldering, sport climbing and trad equally. After just spending 10 days in Yosemite it dawned on me that for the most part the bolted routes that I climb tend to be scarier than the trad ones. I don't know what routes people are climbing trad on regularly but almost all the classics that I can think of in New Hampshire tend to be so well protected that they are less scary than the bolted routes. Recompense, Intimidation, Diedre, Lichen Delight, Robinson Crusoe and dozens of other classics are so well protected that they are only as dangerous as you choose to make them, they are all way less scary than the "bolted" section on Ladyslipper for sure. Climbing at higher grades at Rumney, Shell or Wild River is just easier because you don't have to hang on as long to find the right piece but once you have fallen on nuts and cams enough times I don't think that it's any scarier than bolts. And as far as bold goes I think that high ball bouldering is by far the boldest with the most severe consequences, on a regular basis. This train of thought doesn't apply to folks who are leading stuff like Stage Fright, but that's not the bulk of us. If you avoid sport climbing then I think that you are missing out on great training value. The best routes in the world are trad though. The Rostrum, Astroman, etc.
