To tell you the truth, most bikes ride just as well with a good carbon fork as those with all carbon frames.
My Look KG241 DOES ride smooth as silk though. But my aluminum Fuji Newest is hardly detectibly different.
My Colnago Super rode pretty crappy before I replaced the steel fork with a carbon model.
So think about it some. If those two bikes listed are your only bikes though, you really do need a REAL(tm) road bike. Try riding a 1500 first though.
