Well in that area we agree 100%- there won't be much, if any, warning before cast aluminum bars snap while steel tube bars will always bend. In fact, I don't know that I have ever seen tubular bars actually break though I've seen heaps of them mangled.
From a strictly design point of view, I am surprised any motorcycle manufacturer actually uses cast bars. On the other side of the coin, it is clear that there are so many bikes around with cast bars that they are not suffering any kind of unusual failures. <shrugs shoulders>
Then again, I feel the same way about some rather lightly cast aluminum footpegs some bikes use and yet they are not breaking all over the place either. Still, there are types I simply would not use even if stock to the bike I owned- those shell cast Buell pegs come to mind, I just could not ride with them.
But at least threads like this may provide information to others and help them make a decision about Canyon Dancers.

All I can say to the above is BINGO!!! This alone led me to the LSL bars. Irrational fear? Not to me. It only takes the smallest flaw in cast anything to lead to total failure. I'll take a bend over a fracture anyday. Hairfractures can be next to impossible to spot, right up to the point of a dangling bar.
