My condolences sir I'm sorry for your loss.
Tthree, hope you're a bit better today, it will take a while. Did you have your surgery? So much going on.
Thanks for the replies. Zen, UBZ2, and halves all look viable now to me. Do most of the halves' users, count the indices as in the book or do they double them? Counting them as in the book requires learning very few new indices. Amazing.
