I agree that BCH could still surprise on the upside. I am keeping mine for now for a scenario that you describe and/or Bitcoin bumping into its 1Mb block limit again so that BCH can prove its worth.
This battle is not over yet.
A 2nd thought: BCH is a free hedge against something happening exclusively to Bitcoin.
3rd: a rising tide lifts all boats. Why not wait for more free money?
As we speak, the price of BCH goes up to $250
