Russian Wedding Band - Triple Ring

I seem to remember hearing that making the triple band "Russian"
wedding ring is one of the more challenging projects for a basic
ring and I’m curious if my memory is correct. I have an opportunity
to take a class in this process, but am pretty comfortable with
making band rings. Would there be a good reason to take the class
instead of others that might introduce me to new techniques? Are
these rings so difficult to make? The sign-up is Tuesday, so I’m a
bit tight on time and would appreciate any input the Ganoksin
universe might have for me.
