Sharing a thermal

Lets have a poll. Tell us how you thermal.

I don't believe in a shallow bank for 180 degrees. The trade off in efficiency
is more than offset by getting out of the sink and into the lift quicker.

Reichman's rules: Increase bank in sink, shallow bank as vario rises, increase
bank in lift. My numbers say min sink is 44 ktws, 30 degree min sink is 49, 45
is 52, and 60 is 63 kts.

If themals are tight and narly, then crank 45-60, decreasing with altitude as
thermals generally widen. Like many here, the screws on the instruments are
the 45 degree indicator (a golden nugget from a CSA instructor). I would
rather increase my airspeed than shallow the bank since the increase in
airspeed effectively increases the turn radius with minimal drag effects and
low time lag.

To me, crankin and bankin to get into the best lift is worth it...plus much
more fun!
