First, Campagnolo doesn't have the spline damage issues due to a superior design.

Second, with 11spd I can get exactly what I want already.

I used to train on Centuar cassettes and race on Record when I had Campagnolo 10spd. That worked fine for me. I will most likely go this route again but I am curious about what is out there. Now.

There are some aftermarket cassettes I've seen that combine several cogs in a single carrier much like Shimano does with DA that don't carve up alloy freehubs. My preference is for something like this even though I run Campagnolo.

Last thing, I've been riding long enough that I remember starring at a cog board while I figured out which cogs I was going to install on my 6spd free wheel for the race that day. So, been there done that. It's not what I want to do with my current set up. 12-25 and I'm good to go.
