Thanks for all the response.

I've been using this pattern to form the tripletts: ItiTit (caps showing emphasis) This works fine, though it means re-setting my brains for emphasis alternating between thumb and index. I'm using hammers, pulls & left hand plucks etc. in there as well. When my thumb wants a note on the first string, I find it further up on the second string. That seems to work. I'll probably never get where I can do this smoothly or fast enough to play with other real live people, but it's fun anyway. Now I'll have to find a few more jigs to work out and practice on.
