This just my opinion, but I'd be willing to bet all those stories of broken bolts are due to loose bolts on bikes loaded to the gills riding on rough terrain. Unless you're loading up your bike and riding it hard, about the only thing you need do is make sure they're torqued to spec at all times and chances are even if you do ride the snot out of it your stock bolts will be fine as long as they stay tight.. Just take them out one at a time, inspect it, squeeze out some blue loctite on it and screw back in tight. top bolts are 33ftlbs. (I think) Bottom subframe are 18. Loose bolts tend to shear, but tight ones never seem to do so. Again, just an opinion, but one I'll stand by.
Never pick a fight with an old man.. If he's too old to fight, he'll just kill you..
