[r-t] Double Principles

[Philip Saddleton]

Take a symmetric principle with original lead heads and Queens in the 
plain course (e.g. Duffield Major, Thursday Maximus). The course with 
enormous tittums coursing order has runs back and front, forwards and 
backwards in each lead (at the rows where Queens and Reverse Queens occur).

Alternatively, start from one of these rows, and every pair courses.

Here's my own attempt, which doesn't quite get to Queens, so has a 
maximum of 5-bell runs, but squeezes lots of 4-bell runs into a small space:

Now what calls can I use to get to enormous tittums without splitting 
the pairs?
