upgrade from JMW 10 to 10.5 fpr my VPI Aries 1

Dave,

Thanks for your message,
VPI told me that they will replace my old 10 arm with a new 10.5i arm. Therefore I expect the armtube will be changed and, according to your experience, there should be an improvement, right ? Kim

If you're ending up with a whole new arm, then yes it should be a substantial upgrade. Good luck, Dave

Yes. I just received a whole new 10.5i arm from VPI.
Let's hope there is a substantial improvement.
Thanks everyone and Mike at VPI.

How did the upgrade work out? I'm considering the same upgrade.
