You will EVENTUALLY love that sail. It took me 12 months to grow the balls to haul up the assymetrical on the first boat I owned that came with one.
Despite the Admiral's protestations, on a 10 kt (apparent) downwind sail, I hauled her up the mast
(the sail, not the Admiral) and played with her for half an hour. As I slowly gained confidence, that sail became very useful for downwind sailing. I can't say that you won't have some scarey moments but practice & you will eventually relax. The Admiral never did relax when that beauty was flying but that was her problem.
If you do sell it, you will regret it when your mainsail
is flopping around going downwind and those other boats are floating by you with their assymetricals hauling arse.
