HED3 / HED 3 questions

MrSmith because they flex massively, are heavy, you can't replace the rim when it's worn so you throw away a £400 wheel and buy another one and they ride funny in a crosswind.
their only advantage is aero performance when doing 30k plus on a flattish course

ideal for fixed gear bikes cruising around town.

I have been doing my homework and I checked out the deviation charts and the HED3s come up pretty good with average lateral deflection of 2.31mm - (the aerospokes came last with 5.23mm).

Also the weight is not too bad, 1850g for the pair (by comparison the aerospokes are 2394g a pair).

Are these things a real disaster riding in wind, the information on HED3s website (which of course will be biased) says they are ideal for riding in windy conditions ?

Is this complete horseshit ?
