i carry a cassette removal tool and a 6" crescent wrench.
no longer carry a chain whip.

i think most people torquen the lockring too tight!
when mounting, i turn the tool as much as i can by hand,
then use the wrench for 6-8 more 'clicks.'

i can then use the small wrench to remove the lockring,
holding the cassette with a thick rag. or bit of newspaper.
or rolled up plastic shopping bag.

haven't had one come loose while riding.....yet.
