funny, but the Magnus 2 blade 125 grn is one of my favorite heads, after testing them. I realy like the 100 grn two blade as well. I didn't hear any "hissing" sounds from them in flight, but Some heads that I have heard it from, others have not. Magnus makes some excellent heads, but they are not for everyone, with the exception of the stingers you have to shapen them yourself, and the bigger heads to require more fletching and attention to bow tuning to get excellent flight, but in my opinion it is worth it. I will say that you made a great choice in the Muzzy heads, and they are still my "bread and butter" broadhead.
