I recently bought a spare wheelset but currently only have one cassette (10-speed 105). Should I move the cassette back and forth between the wheels during changes to avoid greater chain wear or does this not make much of a difference?

If it doesn't make a difference, I'll pick up a second cassette, and in that case does it matter much if I buy a different brand cassette? SRAM ones are much cheaper than Shimano.

The chain wears the cassette so it shouldn't matter.

Sram makes expensive cassettes too. They are generally less than the comparable shimano but not by much. Chances are you are looking at a lower grade SRAM than shimano my psychic powers tell me it is a PG-970. Check out the 1070 or 990 it will be more like 100 bucks which is comperable to shimano 105 at 90 bucks and ultegra at 110.

I would put another Shimano cassette on the second wheel, you should be able to switch wheels without having to adjust the rear derailleur. I use several cassettes with the same chain. The important part is to check your chain for wear often. I use both a steel ruler and a Park chain checker. A 24 pin length of new chain is exactly 12 inches. Replace the chain by the time any 24 pin interval stretches to 12 1/16th inches, even sooner if you're running expensive cassettes.

Thanks for the replies. It turns out Nashbar is having a "Shimano sale" today and among the goodies I just ordered is a 105 cassette which exactly matches what I currently have (12-25) for under $50. What great timing. I also ordered the Park chain stretch checker.
