I had a Road Morph on my 47 cm Trek 5200. At one point I had it mounted under the top tube and then it was on the side (down tube). I had 2 bottles, too. I think DH made an adapter to put it on the side.
I use CO2 exclusively, now. I carry 3 cartridges all of the time. Putting the pump on my Kuota just didn't work, even though it is a little bit bigger. Since I have had 2 flats in 10 years, it's fine. I have the pump in my pannier, on my flat bar Jamis.
