RF connection options on Q2687

We have problems with the IMP connector in production. While we can achieve good RF performance on individual units, yield is low.
I noticed in the new Q2687 “Refreshed” documentation that the RF connection options now include a Preci-Dip connector. This is the same connector that was already available on the Q26 Elite (CDMA), so I presume it is tried and trusted.
Is it likely to be more reliable than IMP?
Can anyone else share their experiences with IMP and/or Preci-Dip?

Thanks …
