I also started a 5-something that's not yet rated, but I didn't really give it a good shot. I got on it, though, and I may go back and thrash at it on Wednesday. I also want to work on the balancy green 5.9 in the back room (I've climbed it, but not well), and the black 5.8 with all the slopers in the front room.
I'm actually kind of starting not to suck at this. If I were lighter, I think I'd be a pretty solid 5.9 climber on technique and strength, but because I am a big person, it takes a lot more effort for me to hold myself on the wall and move up than it would if I weighed 140 pounds. My strength is becoming fairly formidable, however, especially when you consider that I'm a chick. I'm even getting to the point where I don't actually hate the physical act of climbing--there are parts where I even feel competent and capable, like my body knows what it's doing and my brain can help.
It never lasts, mind you.
But boy, does this sport do fantastic things for my serotonin levels....
