I am also running Hetre EL tires. I can give a thumbs up to the Pacenti rims. A bit expensive yes, but beautifully made.
What kind of pressures are you running? I find I have had to largely ignore the 55 to 75 psi recommendations on the sidewall, and I am currently using 45 psi front, 55 psi rear. I may try 40/50 next.
