To which I can find no answers on the list archives, have I missed any?

I set myself the following criteria to find touches:

-Use only MBD's Elf to find touches.
-The touch may contain all 8 methods.
-The touch may be up to 8 leads long.
-Use Elf's music scoring to rank touches.

My favourite of the touches I found was:

224 6-spliced, gen. Elf

2345678
4263857 L
3527486 S
7856342 N
6482735 Y
4235678 C-
3425678 B-
2345678 B-

Music = 24

As it contains 6 of the standard 8 and the most music.

Does anyone have a favourite touch of 8-spliced, or an answer to  
Philip's problem above?

Jack
