I'm running 25's on my Boras, both front and rear. Much prefer the added stability using a 25 up front vs a 23. However, if you're buying new and given that new Boras are just around the corner, I'd probably wait for the new ones which will be a little wider with a rim bed that will fit the 25's, or bigger, a bit better. And maybe even be a little more stable, don't know. The only thing about running 25's on the current Boras I find is that when my brakes are where I like them and the tires are inflated, it's a squeeze to get the tires out even with the calipers released (Campagnolo). But no big deal. I guess if you're getting a screamin deal on a set of current Boras then fine, as long as you know there's new ones coming soon. Nothing worse than buying something that you think is current only to find out a week later that a new model is already being released. Either way, I'm sure you'll like them.

At a set of used boras at that price sounds like a steal, I'll go for it and not think too much about the upcoming one. I'll go for 23 in front and 25 behind though for the aero benefit, since tubulars will give you a plush enough ride already.
550 for a set of Boras is a super price.
You will love tubular and i think 23front and 25 on the rear wheel will be more than ok...
Enjoy them

I suspect this may not be true but it's an un-provable hypothesis wither way as it depends on how you are defining "aero".
Wider tyres are only *more aero* (whatever that actually means in the real world) as an interactive component with a suitably shaped rim, according to all of the data that I have reviewed.
The problem is that we don't have a standard definition for "more aero" or even "less aero" - we don't have parameters for the frame, wheels, legs or any other part of the rider-wheel system standardised, we don't have a standard set of yaw angles or air speeds and last we don't have standard cadence rate for our yet to be defined legs making a mess of that unknown airspeed and it's un-defined yaw angle. And for uncertainty factors in trying to produce an accurate, meaningful, quantitative measurement, that is just for starters ...
In a wind tunnel, in a non-revolving test factoring all of the above out, it'll still depend on the precise rim shape and I have never seen that data for a Campagnolo Bora in public-land - not that I have looked that hard because it would be real-world irrelevant anyway (with apologies to all the would-be aerodynamics weenies out there ...)
A Tech-Reps work is never done ...
