As a much wiser head told me once, you are not negotiating from a position of strength when trying to get a new aircraft type, however next ea, when the aircraft is introduced, you are endorsed and the aeroplane is flying revenue service, that's when you are negotiating from a position of strength! If the offered conditions are reasonable the grab it with both hands, worry about the minor details later.
Look at the shorthaul award, in the aftermath of '89 there was no pay for sims, no paxing credit, essentially no pay for calling in sick as well as a number of other conditions that would today be considered harsh. Fast forward a few Eba's/ea's and you have an agreement that is not perfect but results in probably the highest paid 737 pilots in the world with a good lifestyle balance. Get yourself in the aeroplane, the rest will follow.
