Looks really nice - congratulations David!

I hadn't before now investigated use of three types of call in Bristol 
Max. I've now completed a one-part search using normal bobs, singles and 
the 12345T big single. Although lengthy, it is possible to exhaust this, 
so I imagine it is possible to do so for other combinations of three calls.

My results were:

357 hours search time
64.6 trillion nodes searched
96.8 billion compositions found (up to rotation)
