@Murun, If it's carefully stored then there's no rush but if you are in the attic sometime then yes please.
My slightly rambling thoughts on the comparisons are:
I found the Hy/Rds to be a great brake but my double tap levers never seemed to have enough pull on them so frequently hit the bars. I tried having them bleed and changing to compressionless cables housing but nothing seemed to work. I had them adjusted so that I could only just force the locking pin into place so had a niggling concern about another forum member's tale of sudden failure. They stopped the bike though so I used them until they wore out.
So far the spyre's appear to have a slower initial bite but I'm not experiencing the same lever/bar issues with them. They are still on the factory pads so it's possible that once I swap to my preferred nuke-proof ones the initial bite will improve.
I would guess I managed about 20,000Km on the Hy/rds and so a bit less than 1,000Km on the spyres so it's early days yet.
Interestingly I've noticed that I am using a more balanced approach to braking with the spyre. With the Hy/Rd I was very front heavy. I suspect that is because of the initial bite being weaker, but it also means that the rear caliper is still in good condition.
The original brakes which came with the bike were BB5s. I wouldn't wish them on anyone, after almost every ride I would have to adjust which wasn't an easy task.
