Has anyone used Aeronet or Monoura Cage Mounts?

I picked up the Minoura double cage mount and I find that the longer/taller bottle hit me in the butt.  It might just be my riding style.  I may be back too far on my seat.  I don't have a big butt.  My wife says I have a small flat butt like an old white man.  The profile aquarack is my next option.  It also sits lower down on the seat post, where I hear are more areo efficent.

I had a minoura, the bar that was threaded and was the back of the "clamp" bent and would not stay tight, bent it back and it would re-bend.  Emailed minoura several times to try and get or buy a replacement part with no response.  when it was not bent it worked ok, probably used it 2 months last year, one big set of RR tracks did it in.

changed to a x-lab flat wing, http://www.trisports.com/xlfldekit.html  and I like it, had it about a year now, holds the bottles, co2, and co2 thingy.  I keep a tire tool in my bento box for training, tape the tubie on the seat post for racing.
