Sunday morning Class III on Ark?

Just noticed how quickly water is dropping and would like to get my raft/oar frame out another time or two before I'm forced into my ducky. Ideally, I would like to run Pinnacle to Parkdale (or possibly put in a bit earlier than Pinnacle to extend the run). I have run Browns many times, but never this section. I need to be back Sunday afternoon to front range, and this run is not as far away as Browns. This section is at 1600 right now. Let me know if anyone has interested in joining in/running shuttle with me.
