Ah yes...the binge. I have that same problem when I try to diet, lol. You're being good, being good, being good...then you let loose and go wild! Okay then I will support your slowing back down and attempt to anti-enable you whenever possible.
Look at the bright side. At least you "only" made it to VIB level after 3 purchases. If you made it to Rouge after 3 purchases, that would be a much bigger problem, lol.
I used the 130 before I got the 159. The 130 is a great brush for the EDSF too, but it's easier to overdo it with that brush since the fibres are more densely packed. If you use a light hand (or don't mind a heavier application), it does a beautiful job!! I love the 130. It's my favorite brush for the face (eye brushes not included). I use it every day for my foundation.
