Defintely not enough weight to be noticeable. I can see an argument for hardcore 4x4 users and not having glass up there for a roll-over, jumps, etc... but I think for most of us that doesn't apply.
I love my moon-roof. Was on the fence but so glad I got it.
I've opened the moonroof on my 2012 Raptor exactly once in the past 5 years, just to see if it worked. For me, the $1200 was better spend elsewhere.
