Fulcrum racing zero carbons.
Not necessarily a con but, clincher
Not as light as the racing speeds.
Fulcrum racing speed 35
Not sure if as STIFF as the racing zero??
No ceramic bearings
Also in a tubular wheelset, is the rim width as important as it is with clincher?

You should however indicate your purpose (flat, hilly, high mountain, ....) and your ambition (speed, ...) so that we can give you more advices.
BTW, do you use already tubs?
no i've never owned tubs but i have tried the ultra bora and the fulcrum speed 40's from friends and they are great wheels very stiff and light but not willing to dish out that kinda cash at this moment, but i can dish out on the ones i mentioned better price range for me at least.
my ride style is everything climbing descending and flats. i currently own a pair of boyds 44mm carbon clinchers.
alos was thinking baout the campy ones 35mm.
But the main question for you will still be clinchers vs. tubulars. Many riders just want the tubs because of the weight; others don't want to bother with the cons of tubs (spare tub to carry for example).
If you want to "feel" a big difference with your current wheels, go for the Bora 35 Ultra tubular. At least you will "feel" the change with the tubulars, in the ride and in the maintenance.
You're right that rim width is less important with tubs than clinchers, but for example the new Boras (24mm wide) are visually a perfect match for 23mm tubs and a very good match for 25mm tubs - much more so in both cases than older narrow profile rims
Re the fashion point, I'm not alone, with the obvious consequences for re-sale value ...
Stiff, Light, Aero - Pick Three!!
I've found the older Boras (pre 2015 tubular), best fit tubular tires from 22mm-24mm in width. You can run 25's but the fit is not as good as on the newer Boras, where a 24-25mm tubular is really a perfect fit. I've tried 23mm Veloflex Carbons on the new Boras and they are just fine, but really do expose the rim brake surface a little more than I'd like to the dangers of the road etc. For the new clincher Boras, I think 23-25mm tires both fit well, and sometimes the decision is based on clearance in your frame. The fit of a particular clincher on a particular rim is very dependent on the rim width, versus a tubular which is encased in it's own shell and the inflated size will be the same regardless of width. The only thing you need to be concerned with is the match between the rim bed and the tubular tire radius, as I tried to explain above.
What frame and components are you using?
