I know it is supposedly very hard to mount tubeless tires, if this is not true, please let me know.
I am running Campagnolo Eurus 2-way fit with Hutchinson Fusion 3's in tubeless mode. I do not find it particularly difficult to mount the tires and flats are a thing of the past. I run mine with about 30-40 ml. of Caffelatex. I am able to get the tires to seat with a floor pump, using soapy water at the bead to help the seal. In two years I have had only one flat, due to a large gash caused by glass that destroyed my rear tire. Other than that there were a couple of occasions where I saw some Caffelatex being spit out through small holes that self-sealed. In those instances my tire did not lose noticeable amounts of air pressure and I continued my ride without doing more than wiping a little Caffelatex off of my seat tube. I have had so much success with the Caffelatex, that I have not tried Stan's, though it sounds like people have good results with it as well.
I have ridden some similar Hutchinson clinchers (i.e. similar to the Fusion 3) with tubes and the ride was not very good. However, the Hutchinsons used in tubeless mode have a much smoother ride; at least as smooth as any Michelin or Conti clincher run with a tube. And I would say that the Fusion 3 lasts longer than the Michelin or Conti, so though the price is steep, you get a tire that lasts longer and you should save money on tubes.
