In reply to Juggler13:
I suppose it is a very subjective topic. I do know folk who climb purely indoors and although I can't understand the rationale behind it, I know enough to know they enjoy it. I climb indoors quite regularly myself, especially in bad weather, but I consider it just training. I keeps me in practice for when I get out onto rock.
I've never fully understood indoor climbing competitions, though that's not to say I don't respect the levels at which these folks climb...it's far beyond anything I can do. Climbing is never about scoring points and getting trophies for me. It is about getting out and forgetting everything but the climb...an escape from reality (everybody needs one, else you'll lose your mind). As corny as it sounds; it's freedom.
In responce to your origin post; I always suspected that you could use features for feet on any route unless specifically stated otherwise. That said, I've never payed much mind to the grades of an indoor wall...I don't even think my local wall is 'officially' graded.
