Here are the maximal sets of splicable methods from the standard 41 
(ignoring lead-end variants and lead splicers).  As I said, a very short 
list.  I would like to see the same thing for the 147.

In course:

Bo Ne
Ak Nb Cl
Nb Sa Cu Cl
Ak Ch Sa Cu Cl
Nw Ak Ch Sa Cl
Bv Bo Du Cm Yo
Nw Sa Ch Cu Cl

Out of course:

Lf Ak Wm Nw
Ip Bo Cu Cm
Sa Bo Ws No
Bv We Cu Yo
Lo Ip Cu Cl
Lo Yo Cu Cl
Ip Cu Cm Lo
Ip Cu Cm Ne
Ip Cu Cm Yo
Ip We Cu Lo
Sa Ws Ne No
Lf Ak Wm Nb Ne
Lo We Du Yo Cu
We Yo Lo Bo Bv Du
