H Plus Son rims - are they any good?

Oh yes, and Hippy's expertise in such matters does show, and I think he should be listened to:
***"It's obvious the rim exploded at the valve-stem drilling in the rim. What most likely occurred was that the rider made an error we all have at some point; he didn't properly nest the tube and tire within the hooks of the rim's cross-section. ***
What usually happens when you do that is your tube slips past the wire bead of the tire and forms a bubble. You can ride on it like this, but it will eventually explode. From my observation, it appears that the rim's inner wall was weaker than the tire bead and it took the released force the hardest resulting in the damage shown above."

I don't think I said that. :S

Sorry, it wasn't totally clear I was quoting that blog below the text.
