As i know you love the Stoney Catchment, there's the "classic" (probably never done before) of the
Stoney Traverse ™
Layby Top -> Layby Bottom
Ivy Green West -> Ivy Green East
Streaks Top -> Streaks Bottom
Merlins Adit -> Carlswark Resurgence
Fingal's Cave -> Triple Hole (!?!)
Keyhole Cave West -> Keyhole Cave East
Windy Ledge Cave West -> Windy Ledge Cave East
I reckon there's more underground than above ground on that trip, until the walk back to the car.... And no pre-rigging needed
Obviously the best way is with a pre-beer before each underground venture 🍻
