i think the left kneebar thing is a red herring. here's my beta from the jug at the top of weedkiller:
LH to good flatty left, foot up and RH over to the crimp hold to the right of the hold the guys using there. bring feet up somewhere and span out left to the sloper (guy's got his left hand on this), this forgoes the kneebar pissing around. Then put right heel above the RH adn get a heel-toe in, pull up (rather than just trying to hang on it) and reach to good 3finger crimp over the lip with RH. the clamp something/heeltoe with left foot and bring LH over to the crimp rail on the good bit (clip). match rail. now (and this is the bit the made the difference for me on the lead and turned a powersapping bit into steady climbing) put left heeltoe on top of the sloper hold (you had your left hand on this earlier), smear right foot on rock in obvious place, and reach up for good hold far above with RH, match the lessgood bit next to this with LH without moving feet, cut loose, put right foot up on lip, slap to good incut sidepull, swap feet, pull over for jug.
