There's only one deviation you'll need to avoid and that's for the main hang from the bridge to the floor of the main shaft. You have a number of options for routes here, although if it's wet, you've really only got one. I think you might struggle coming up with a decent belay to rebelay from, though. If it helps, the deviation from the furthest hang is really quite nice and opposite a ledge so you can push yourself out using your legs. Very little stretching or awkwardness required.
