Thanks!
At the risk of getting my a$$ handed to me, I'm going to out on a limb and say I don't think the type of rotor head should make any difference. Regardless of head type, at some forward speed the retreating blade will stall (will be unable to produce equal lift to that of the advancing blade). So, to answer your SPECIFIC question, I'd say its just as easy to get into retreating blade stall if you go too fast, regardless of the head type (I suppose thats why we have performance graphs which tell us stuff like Vrbs for a particular set of environmental factors).
Feel free to disagree, but thats my 2cents worth.
