Hi Woodie
Your statement about Hyperions batteries is not strictly true. What Hyperion claim is that the Gen 3 batteries will hold up several time longer than equivalent cells on a similiar charging regime not no impact on longevity. In short if you hammer them they wont last as long but will last longer than other makes of cell.
I have just bought four sets of packs for my Winds S and I dont intend charging them above 0.8C. ( To prolong my substancial investment)

Other manufacturer have made similiar claims ( eg Flightpower) but so far Hyperion are the only company to have their claims independently verified.

On a side note Hyperion are the only cells I have seen that are delivered in a custom made cardboard box with heavy padding inside. Not the cheap plastic bag most other manufacturers put their product into. Also the standard of construction of the packs is excellent. Much better than some other more expensive cells.
