I still do not get all the fuss about trad climbing. It ain't rocket science. i lead the same grade regardless of if it is bolts or gear. the only time it becomes a big deal is when the gear sucks but that is the same with bolts or gear. If it is G rated weather it be gear or spurt there is little difference. if it is r rated and it is over good gear then it is no different than R rated over a bolt.
except that you don't have to decide where to place bolt. One of the plaisir is to decide that my rock number 4 will hold a fall of 20 feet and I will not be injure in the fall. so, I can climb 10 feet over my pro and find an other protection, take the risk to go over or bail (fall on the pro) That happen in trad when you use the technique describe in mountaineering freedom of the hill and when you hire a trad guide. The guy who invent friend climb 25 meters over a tricam. Many sport climber don't even have tricam. In a route, some good trad climber and I, even if I don't test it personally, can place two rp and pull over an hard move knowing how to put it togheter. it is not a 25Kn bolt for sure. A pro can be good at the end of a pitch and not good at the bottom. It is not a rocket science, but it is a lot of small think to understand, not to remember, to understand.
When you did all the 5.7, all the 5.8 and over, you begin with the g rate, try some r rate and finish with x rate... after you climb a grade over, 5.7 to 5.8 for example. there are gem every where and some routes are not climbing because people will respect the climber, but because you want to know if you have the same knowledge of the first ascender.
For must people, it is the same and when they learn that there is an accident in recompense, the book or somewhere else...they stop climbing because they don't understand why and where they made a mistake. Unfortunately, in general, it is not those who said that it is easy who fall...but innocent newbye who think that there is no difference.
