I don't know if I just got lucky or if Parma uses a different gluing process than Jaco but I know a few others with similar experiences to mine with the Blackhawks.
Cheers,

My Blackhawks pealed just the same as my Jacos and had problems with the front bearings being loose. From my understanding Jaco makes the Blackhawks for Parma so the process would be the same.
