It's always the left crank that snaps off, because it gets the greater stress.
You've go to be kidding. In 30 years of riding I've never seen anyone snap a crank. Even my 230 lb brother who's been riding the same SunTour equipped bike for 17 years never had a failure. Square taper works fine for most riders. The other innovations, I say that lightly, are basically BLING. They're just ways to sell more product.
