Superstition? So I take it you never personally experienced using T & S wheels? Doing that, more or less, in essence makes a bigger hub and stiffer wheels. Grab two spokes where they cross and squeeze, then see how much they move. Also I have twice had a spoke snap and the wheel pretty much stayed true enough to still roll thru the brake pads. But, it is something fastidious to do. On a Rando bike, no T&S spokes and use low flange hubs so I have the longest spokes and a slightly softer and more forgiving 14+ hour endurance rides.
