we've talked about mac studio fix, but what about STUDIO TECH?

I got some of this a couple of days ago, and have been trying it. Surprisingly, it's working out well for me so far. I thought it would be really heavy, but it's not. In fact, the Studio Fix seems heavier to me. Also, this is staying on better than the Studio Fix. So far, so good!
 
Great thread! I have always wondered about Studio Tech. I am usually weary of cream compact foundation, bc most I have tried are way too cakey/thick. Just curious- what kind of brush do you studio tech users prefer? 190... 187... 109? Thanks!
