I have a set built with A23s and a set built with the BHS (kinlin) wide, which is the same rim in the Boyd Vitesse. I mainly use them with 23mm tires at 90/100psi and I weigh 175#. I find the cornering grip and braking grip improved. It is most noticeable on high speed corners on not-so-smooth roads where the chatter is much reduced and I have more confidence to lean the bike over. Much of the same effect might be gotten using 25mm tires on standard width rims, although the straighter sidewall aspect when using wide rims at least makes sense to me that it could be helping here.
And for comparison I still have a bike running 25s on 19mm rims also at 90/100psi but I do prefer my wide rimmed wheels.
I'd also like to say that the BHS rims built into what seems to be an incredibly stiff wheel. I have 2 other sets with similar spoking (one of them is the A23s) but the BHS really stands out. It is about 30g heavier per rim, though.
I actually have a new PT on it's way that is going to be laced to a HED C2.
