In reply to edhawk21:
The grade is the grade is the grade. It can also depend on how you top rope. I see many novices indoors almost being winched up routes. Even with a reasonably taught rope you do get lots of subtle assistance that may not be obvious at the time. I find it quite amusing when they get down to the ground and walk around their mates saying they've just climbed a 6b or a 6c or some such nonsense. Certainly in trad, routes are graded for the lead, with sport it is mostly graded for the Redpoint but again the lead.
On trad if you second, say an E3,5c, it's reasonable to claim you have climbed a 5c but in no way have you climbed an E3. For myself I don't really think I've climbed a route unless I lead it, but that's my personal ethical stance.
Climbing wise I climb better when I lead but I do not find that there is a huge difference between the lead and the second especially on sport.
