Glenn, like PEB said, they are awesome.
I have not had a big get off, so can't comment on the strength.
They do seem stronger than conventional bars.
I like the bars low and back so I can keep my elbows bent and my head right above the # plate.
I've had wrist problems ever since I hit another rider head on.
With the Flexx bars, I can ride with no issues at all.
I have the 12 degree woods bend bars, but would prefer the 10 degree ones.
