I just used the Pantin on a run to Dolt. This is an extremely efficient way to ascend a rope.
I went with a Pantin left and a left hand ascender at the top, connected to me by adjustable daisy. On the right, I had a right hand ascender placed below the left hand, with an aider, tethered to me by adjustable daisy. At the belay loop, I ran a RollnLock on a clepsydra. I had 3.5 points of contact on the rope. No chest ascender.
The method for ascending was the same as if I had two aiders and hand ascenders with a Grigri at the belay loop. Essentially, I swapped the left aider for the Pantin, and swapped the Grigri for the RollnLock, although I’ll probably go with the Microtrax moving forward. The Pantin connection will disengage the RollnLock cam if you’re not aligned vertically.
Cleaning was easy. The only part that was difficult was ascending pitch 5 because the rope hangs in jagged overhang terrain where you need to put your feet on some rocks that jut out. I ended up disconnecting the Pantin and ascending in a normal method.
