Quite a different story if we had a world-class drop tower. I know, tradition, tradition.... have BOTH then... 
I can't agree with lamest. Not everything in the park has to flip, go fast or give you airtime. I LOVE an awesome coaster (obvoius with 27 rides on Fury) but I still love something relaxing and visually exciting too. Now, I do agree with malfunctioning, but it is an older ride and fixing it will take time, but I can't wait for it to reopen.
If you want a new drop tower, how about getting rid of the Drop Zone and replacing it with something more intense for that area. That would be much nicer than killing the sky tower.
