105 5600 - 12/27 - probably 1000 - more than likely less, but want to be realistic - it's very nice...

Campagnolo 12/25 - Not entirely sure what level, so let's assume Veloce? 1500-2000 Miles, this was on my rider and I converted over to 11 speed.

I ran Shimano for a short time, switched to Sram for even shorter time, before going back to Campy. Then went to Campy 11 speed. So these cassettes saw little use, with exception of the campy 10 speed which saw a full summer.

Let me know...
