In reply to Steve Perry (Pezz):
Worth learning a set of dirty sport climbing tactics for dogging to the top/lowering off a sport route that's too hard for you.
keep a 6mm maillon on the back of your harness - then it's always there if you need it.
By clipping in directly to a bolt, you can often walk your feet up and lever up high enough to get the next draw in. Then yard up on that and continue the process.
having quickdraws with fat tapes makes it easier to hang on to them while you dangle/clip the rope, yard up on them, etc. It's surprising how many moves or sequences which are too hard to climb clean, will work ok for getting the next draw in and grabbing it.
As Morgs says, clipsticks are awesome, they make all of that a lot easier and you know that getting to the top is always an option as you can always clip in to the nearest bolt, lower down a bight of rope and haul up the clipstick.
Having the confidence that even if the worst comes to the worst, you can still dog/frig/clipstick your way to the anchor to get your gear back, gives you much more confidence at trying stuff above your grade (which is the point of sport climbing, really)
