> Well I'll hold my hands up and admit that I'm no sport climber, but I'm fairly sure that sport grades are meant to take sustainedness of difficulties into account. By your logic a sport route consisting of easy climbing with one English 5a move would get the same grade as another where every move was 5a, and that is surely not true? If you're climbing places where the routes are graded like that, then I would suggest that whoever is grading them has got it wrong.

--- it is true, you can check sport routes all over europe. even worse - they sometimes keep the same grades like they were in the 80's (in france), when there were no hard grades, so 6a+ then would get 6b+ today.

There aren't really any rests (although there's quite a few disappointing half-rests which just allow you to get more pumped whilst you kid yourself into thinking you're recovering). I didn't lead it, but the gear seemed fine, but it's sufficiently sustained that that isn't really the problem.

-- show off by saying i did an E1 ? im not that dumb... (and saying it should get 5b and not 5a is showing off ??)
back to the point ... thats exactly what i mean ! one person finds a rest where another missed it. and on other routes the other climber manages to rest on an overhang since he goes to the gym a lot, while the first climber gets pumped. its not very objective saying there are only half rests. but we can both agree there are loads of placements.

> Ignoring the fact that this sentence doesn't make any sense, it would seem that your mistake is in trying to look at this like a mathematical function where you plug in some factors and out pops a grade. If that was the case, then why are people still arguing about the grade of Three Pebble Slab?
--- im saying that two parameters describe best two other parameters and not four or ten...
but my main point is that if im climbing trad i would personally prefer an overall danger grade than overall technical grade, or mixture of the two, since :
1. everyone wants to get back in one piece rather than complete a route. (a strong beginner in the outdoors wouldnt want dangerous routes , and there are pretty dangerous E1's sometimes. old threads as placements , etc..)
2. its more objective to evaluate overall danger than something like sustainability. (like I claimed above).
3. it makes more sense (to me..) to separate technical difficulty from the placements aspect.
