After reading a thermal flying guide * that said pilots often don't bank their gliders steep enough in 360 turns while thermaling. The article went on to say that the best indication of bank angle is the amount of time it takes to complete one 360 degree turn . Higher bank angles mean faster , tighter 360's I guess.
So is there an optimum bank angle for hang gliders while flying thermals?

There is not one single "perfect" bank angle for "all" thermals ...... **But there is for the one you are currently in at that time.
By that I mean you need to maintain the best angle / speed for the piece of lift you are in, at that time. That can change throughout a your climb.
Listen to your instrument, feel the glider and what its telling you to find that sweet spot of "the best climb rate"
So basically, make the beeper box go as fast as it can!
Whether that be a steep bank angle (narrow thermal, gotta bank it up to stay in the core) or flatter fat wide thermal.
If you are bored, have a listen, starts off about 5 min mark, (boring for awhile)
about the 5:50 mark starts getting better.
This thermal changed a lot down low, some good pieces, some narrow strong stuff, leading up to a consistent strong fairly wide climb.
The thing to watch is how my angle and speed change, while the climb rate stays close to the same in some of it.
Just a general piece to reference
