[r-t] Caters stimulus package - new methods

> Anyway - a good start, Ander, to your challenge?

Yes, definitely!  Looks like some great ideas here.  In a rush now, will 
look properly soon...

One quickie: for many years I have wondered about the cyclic principles:
9.1.9.1.5.9.1.9.1
and
9.1.7.3.5.7.3.9.1
Both have great plain courses (of 81 changes!) - can anything good be done 
peal-wise?
