In reply to remus:
> Is it really that different?
I'd argue that it is quite different, but not in a way that would be resolved by labelling all trad routes after practice as 'head point' and all sport routes after practice as 'redpoint'. To me, the distinction is between practicing the moves because you're going to hurt yourself if you fall of (head point) or practicing the moves because they're really hard (redpoint).
For example, I led
Low Profile (E5 6b) at Avon after practice (all on lead, but still practice). It's safe enough that I wasn't worried about injury if I fell, but I needed to figure out the sequence on the headwall to be able to do it. I suppose you could argue that the route in question is pegged-up pseudo-sport, but I think I'd feel the same way about a safe route protected by bomber wires. Actually, case in point would be
Mirage (E3 6a), which I also led 'clean after practice'
Of course, I agree completely with you when you say
> the underlying idea ('after practice') is the same.
This is more a response to the OP suggesting that drawing the head point/redpoint line sharply and the trad/sport boundary (itself quite a blurry line) wouldn't necessarily solve the problem. In fact, I think the current solution ('clean after practice') neatly avoids the issue!
I don't normally get into arguments about definitions... I suppose I can justify it here because it's not an argument yet!
