In reply to cider nut:
For me, it's not that there is a grade I want to climb - it's more that there are specific lines that i want to climb.
The graidng system merely provides a guide as to what may or may not be possible for me at any one time.
I'm surprised that the OP says he has no real desire to push into E2 unless he thought a specific route would "go". Surely, if he spotted a perfect, beautiful line, with good gear etc, but knew it'd be really pushing it and he'd have maybe only a 20%-50% chance of success (depending on conditions/fitness etc), he'd want to try it... isn't that what it's about or am I missing something.
If we only climb things we think will "go" where's the fun? I personally like the uncertainty, the adventure of trying something that there is a good chance I can't do.
It's surely not about reching a particular grade and then bein content, unless we just want recognition from peers etc. Surely it's about climbing nice bits of rock and pushing our limits both phsyically and mentally?
