You have received quite a few replies but so far I don't think anyone
has has distinguished between written check lists as recommended by FAA
and mnemonics usually favored by glider pilots.

I use a written checklist to ensure that I have done everything
required to prepare myself and the glider for flight. That is
completed before grid time and rechecked before the contest launch
starts. After that I use no written checklists. I shudder to think
how those that can't extent the gear on short final would cope with the
task of finding, reading, executing, and stowing a checklist. I'd
rather have my eyes outside.

Mnemonic CBIFTCB covers everything I need for takeoff. I use WUFST
(water, undercarriage, flaps, speed, trim) for landing.
