horses for courses I suppose. I did the ABC's & CBA's in full in the early days, but these days if my AV pipes up I can dismiss it immediately, without having to resort to reasoning. I suspect that, in effect, it's pretty similar to AVRT, even though the path to that point has been rather different.
if someone finds they're trying to do ABC's & CBA's from the ground up each time & they're not working for them, then AVRT may well be a better choice. it's always good to have options
