I'm curious what others are using for inter-thermal cruise speeds for
modern 15m (and 18m I guess) gliders like the Ventus 2bx, Ventus 2cx,
ASW-27, ASG-29, Diana 2, etc (add models as necessary).

According to a fellow club member (Discus 2), if the day is booming, fly
80 kts, if the day is good, fly 70 kts, if the day is so so, fly 60 kts.
YMMV.
