Havent done it, (above my grade at the moment)looks good though, you thinking of doing it "trad" or top roping it?, apparently the gear's crap lower down, as with anything on the Roaches, try it early in the year, most of the first ascents were early (Jan/Feb/March), before the green slime has chance to grow, you might get a better response on one of the dedicated climbing sites such as climb.uk, good luck,
let me know when you're thinking of having a go, I might come and watch.
