Not much activity on the OBOW for sales - too bad, I was looking for used gear when contemplating a recent Tom Bihn purchase. There are healthy for sale forums for outdoor gear that I've used extensively.
I just got the Synapse 25 in black halcyon and I was surprised how rigid that fabric felt (at least new). I almost got the Pilot, and would have picked ballistic at the time, but after getting my synapse, I'm not sure. I really like the look and feel of the halcyon.
All that to say, if OP or anyone is interested in selling a Pilot in black halcyon, let me know by PM and maybe I can help you fund your replacement bag.
Best,
