From what I've heard, relatively few people have figure skating blades break - and they are almost all doing split jumps (which create a lot of lateral force if your feet don't get together again enough before you land) or various high level jumps - where an under or over rotated jump can again create a lot of lateral force. I don't know whether the original poster does split jumps or high level jumps.
Of course, the biggest benefit of the weight saved and the claimed reduction in impact force (due to the flexibility of carbon fiber) of Revolution blades may be for people doing high level jumps. If the original poster doesn't plan on them, do you think Revolution blades be expensive overkill?
If Paramount blades get rivets, they would look almost exactly like Ultima Matrix II blades. I think their main selling point has been that they were several grams lighter (not a lot), approximately the weight of those rivets. Though, now that I think of it, it is possible that Ultima uses stainless steel screws or bolts instead of rivets - but they are glued in place. Do you think Paramount is a big enough name to compete with Ultima without that minor weight advantage?
(In my older Matrix I model blades, Ultima used bolts, which weren't glued in place, but of a much softer material, which were problematical for various reasons, and I re-tighten them once/month or so. I still think their relatively cheap interchangeable runners were the right way to go, even if Ultima's bolts had problems.)
