UFC196 really made an impression on you did it [MENTION=12409]Sir El Stiffy[/MENTION]; ?? lol
I haven't had any problem with froth ever since that True Protein debacle. In fact I never had a problem with Bulk Nutrient's WPI/WPC being frothy at all. Right now I am sipping on their strawberry WPC with 120g imported frozen mixed berries and topped with 306mL of ice cold HiLo milk blended in. And there is absolutely no froth in there at all, even when I fill my mouth up and gargle it.
I hope you're using ice cold liquid to blend your protein shake, because anything lukewarm or warm will turn it into a cappuccino without the cappu.
