In reply to DrJP:
Your best bet by a significant margin would be to go from the ground up, using a clipstick if you need to. Due to the steepness it'd probably be 7a+ just getting the draws in from abseil, harder than the route itself!!
If done this way you may need to do a few moves to get from the top bolt to the lower-off (as the clipstick won't bend around the top lip), but it'll still be around a thousand times easier than getting them in from the abseil.
Same goes for working it, a top rope would be a nightmare as you'd be constantly swinging out, so stick to going bolt to bolt until you're ready for the redpoint.
Have fun (and good luck)!
