See the "angle" posts below (below this branch).
Keep in mind that in my comments in the "angle" branch below, I've "retreated" somewhat from my earlier statements.
The wrist strain (hyper extension) really comes into play with a large feather in a low angle stroke. The wrist strain is almost non-existant with a feathered paddle in a high angle, modern stroke.
I was not suggesting that it was a "trueism" (which implies like a 100% incident rate). This means that I expect exceptions. Your "one" example could be an exception I expect. It doesn't contradict my general characterization of the population (which could be wrong).
It's the "statement X is wrong as a general characterization of a population because I can find exceptions" thing I "object" to!
It's kind of like somebody saying that the statement "humans are in general about 6 feet (or whatever)" is wrong because pygmies or 7 foot tall basketball players exist. (Such exceptions would invalidate a "humans are -always- 6 feet tall" kind of statement.)
