Keep the mnemonics (USTALL, TWA, GUMP) as safety nets.

TWA = Traffic, Wind, Altimeter (or Altitude)
GUMP = Gas, Undercarriage, Mixture, Prop (obviously for Power)
USTALL = Undercarriage, Speed, Trim, Airbrakes, Lookout, Land
see http://www.soaringsafety.org/images/ustall.jpg for a USTALL poster

I find myself using GUMP even in my 1-26...obviously completing that
checklist is very quick...and it prompts me to remember the other
two...which are similarly quick (Trim on a 1-26 is of marginal utility
on approach).

Nevertheless, they get me set up for safe landings...whatever I'm
flying!
