In general, cores for transformers should have relatively high mu
and low loss. #43 material by far the lowest loss, while the other
materials all have about twice as much mu. If I had #43 of suitable
size, I would use that first.
Tom Rauch actually designs transformers for Beverages, so if he
gives you different advice, take it!
BTW -- you DO want lots of loss in a choke that is being used for
suppression or as a balun.
