I have a pretty strong drilling on it...stronger than I normally use. I normally like 5 inch + pin-PAP distances, but I went 4-4.5...
The comparison to the TNV wasn't necessarily strength wise...it was in regards to how the ball rolls -- it has that really heavy roll, that is still pretty angular. For some, it might be as strong as the TNV. For some, it might not be.
In my experience, I have never seen the TNV be AS STRONG as people make it out to be. It's still a medium-heavy oil pearl, and is thusly subject to carrydown, etc...
Put a weaker drilling on the NHP, and you should have a nice step down from the TNV.
