Fender 9050ML's sound great on a MIM jazz IMHO.
Sure, you may need to set up the bass after putting them on. But don't expect the neck to get damaged from them.
I currently have those on my MIM pBass deluxe, which has a jazz neck. The neck is just fine. These strings also seem to get a bit easier to play as they break in, and will give you a good old school sound.
Good luck!
