Review by APD
Bought the 1234 version for a steep course with a tandem. Used with a Deore rear derailleur, our usual cassette is an 1128. Added several extra links on the chain and adjusted the B-screw a good amount on the derailleur, had no issues and good shifting performance.

This was a very useful choice to have purchased the new cassette because it has allowed me to ride (crawl) up hills without quite the previous difficulty.
Plus, there is a higher top gear that I've not yet reached.
