Difference in Cassettes.
Is there a performance difference between a 105 and Dura Ace cassette? I know the DA is lighter, but can one feel a true performance increase between the two (ex: smoother shifting?)

No. Even saying the Dura-Ace is more durable is a stretch. The only difference is in finish, material, and weight.

Plus you can let "full Dura-ace" roll off of your tongue instead of "Dura-ace-with-105-cassette" when talking to your cool cycling buddies.

The 105 cassette will probably outlast the DuraAce cassette

The titanium cogs on a Dura-Ace cassette are lighter weight, but less durable than the steel cogs on cheaper cassettes.
The higher end cassettes also mount groups of cogs on carriers. This potentially makes the cassette stiffer, and less likely to damage an aluminum freehub.

It is true that the DA is the least durable, but lighter. I do run them (9sp is super cheap on ebay - 12/23 used for $17 2 weeks ago) on all my bikes. If you keep the drivetrain clean, they last plenty long - thousands of miles easily.
However, if I was to buy a new bike with an Ultegra cassette, I would feel no need to change.

I ride Ultegra, Dura-Ace 9, and Record 10. I can see no difference in wear rate in the cassette cogs or chain.

I just purchased an 11-23 105 cassette from PBK for under $50 (freeship). This thing weighs 2 ounces more than the comparable Ultegra cassette. Wheeee!

Dura-Ace makes you faster. Don't ask how...it just does.

It seems to me that steel should be more wear resistant than Titanium but mine wear about the same, very little.
