In reply to webbie88: II think you can do without the strimmer, just put some trousers on and walk through the grass!
You should check who owns the crag. They might not be happy if you just rock up and start ripping plants out of their rock.
Be aware of loose rock. If it has never been climbed chances are that there will be some loose stuff on there.
Don't expect anyone to pay any attention, I have climbed several new routes of a similar style to what you are expecting, and other than one person finding them on here and going for a look nobody has paid any attention at all.
I would suggest if you have gained permission to abseil in from the top down your line, checking if the rock is solid and having a go at some of the moves. Or just strap on a pair and go for it from the bottom. What's the worst that could happen?
