Being too tall for some rides???

I knew when I was at PKI last year I was literally an inch or two from being too tall for Delerium; and I've grown about an inch, so I probably can't ride Delerium anymore. :( Correct me if I'm wrong, but doesn't the floor on maXair lower farther than that of Delerium? I also think that Delerium hangs closer to the platform, because I remember almost being able to touch the floor even in my seat before it lowered on Delerium. I'm 6', close to 6'1" and can almost put half of my foot on the ground at Power Tower sitting upright. Surprisingly I don't have very much trouble with CCMR or DT.
