It is like saying do you want butter pecan or chocolate. Do what you want to do. Seriously.
If you want to do a conversion, awesome! Then fork over $160 for the wheels, about $100 for other stuff, and ride it.
If you want a Kilo, excellent! Price it, buy it, ride it.
The economics aren't much different (a few hundred bucks at most). It is all aesthetic. You won't be wrong, if that is what concerns you.
** note: this opinion does not hold true for any bike with French threading or vertical dropout. Nor does it hold true for the midget bikes that clowns ride in circuses. All are notoriously difficult to convert to a daily ss rider.
