I would say that there's far less stress on a wheel on the bkool compared to out on the road. Apart from all the crud that gets into your bearings and the rough surface that puts massive load on your wheels, you are generally not putting any lateral load on your wheels and spokes because you have to learn to ride with a style that avoids the tipping motion that you get when you're out of the saddle and pushing hard up a hill. Even when out of the saddle on the turbo you are instinctively avoiding lateral forces. Same goes for carbon fibre frames IMO. Far less harm on the turbo than out on the road.
So if I had my perfect set of wheels which would be Mavic Ksyrium Exaliths then I would keep them for the turbo and for racing out on the roads, but seeing as I don't race out on the roads, they are just too much of an extravagance.
Cheers Bill, I will pluck up the courage and use my powertap rims on the bkool - will be interesting to see how the numbers look. (my gut feeling they are pretty close).
