Hello friend. Your boy seems like a good sport, and a splendid climber. While you're living vicariously through his accomplishments, remember to keep a helmet on him. And please don't teach him to talk like a rap artist (like his dad).
I don't think 5.13 is special unless you're climbing it in very good style. I suspect you've done a couple of these, but I doubt you do them any faster or in any better style than the next mediocre athlete (like I) could do. I've never done one, but I flashed Equinox on a top-rope, so I assume I could add a couple ofletter grades by adopting your strategies. Maybe I'm wrong. But I'm not really interested in knowing either.
The point is, the traditional approach to mountaineering (rock, ice, whatever) requires everything the sport climber is doing and more. You have to worry about protection, about safety, about leading out on moves when the pro below you may be questionable and you don't know whether any good pro exists above. You have to worry about possibly getting a bolt in on lead, or maybe you just back off. One way or the other, the demands are higher, the adventure greater, the mess you leave is far smaller.
Sport climbing? Virtually every requirement described in the previous paragraph is bypassed. You can spend days or weeks working one pitch, you can hang, yard, top-rope, whatever you want. I think Dwayner's point is accurate, which is that 5.13 isn't really that great a leap above hard 5.11 or 5.12, when so many of the requirements of traditional climbing are removed. It doesn't matter whether you've done one, or I've done one, or Dwayner's done one. If sport climbing tactics are employed, it's no greater accomplishment than climbing a 5.12 in good style.
