Simon – what a great response! You show me two things I hadn’t thought about. 1) that there is a speed difference between pick and roll, and 2) that I completely forgot that I could tell pick/roll how many elements to pick. That eliminates the need for my for ^8 loop.

You showcase better than me the point I’m trying to make in part two of this (I don’t know whether you read that one too?): that style and choices influence speed.

In any case I’m glad that by showcasing what I don’t know I learn so much from people like yourself. Thanks!
