Thank you S.C. for your detailed answers and the wealth of information you provided.
My own concern, (as if that amounts to anything). is that there is no information of any kind on there being any branch of Shaolin in Shandong. Moreover, the period of nearly 800 years of non transmission for Tanglangquan cannot be ignored.
Yet, in your theory, both the fact that there is no such information on a Shandong Shaolin nor a tradition of transmission of Tanglangquan, (in fact all known manuscripts that I have heard of say that there was no transmission), seem to deter you from saying that there was or could have been. This seems problematic from the outset. But I guess you have your reasons.
On an unrelated note:
I offer some information on some of the participants in the meeting (you have been more than generous with your research. Mine is not as extensive but may show why I have some doubt about the meeting ever taking place, regardless of it being at Henan or Shandong):
The tradition holds that the meeting of the Eighteen Champions was held at Shaolin in Henan with Fu Ju holding court over the meeting. In fact, tradition holds that Wong Long was offered a position with Tai Zhu (976-997) in his military, which he declined. (On a positive note, it is also said that such personal selection of officers by Tai Zhu was not uncommon, though I have not read of anyone refusing). So far, so good...
But, as for Lin Cheong and Yan Qing, they were supposed to be outlaws against the Song Dynasty from the early 11th century to the establishment of the Southern Song regime in 1127 about
a hundred years later than the meeting at Shaolin. Perhaps they time traveled?
For further clouding of the issue we have only to look at Han Tong who defended a losing side:
"The child emperor of Later Zhou was forced to retreat. The only resistance at the court came from Han Tong 韓通 who died and was buried with great honors by Zhao Kuangyin". (who later became emperor Tai Zhu)
before the meeting at Shaolin could have taken place. Perhaps he came back from the dead...?

The tradition of the meeting is intriguing but the more one looks at it, the more it seems just a tradition.
You mention other reserach that is under way by others. I would greatly appreciate your sharing if you find that they have published. Though we may disagree on methods or theories please know that I have great regard for your work in gathering information. You seem to have many good sources.
