Are both blacktrack and Blitz&Glits Neccesary?

[RoseMe]

I was wondering how many of you have both, or thought about having/using both? I already have blitz and was wondering if blacktrack is necessary as an addition? Can you really make very different effects from each?
Thanks so much for your comments!

I have both and while I don't think having both is neccesary, I do like the variety. Blitz and Glitz isn't as dark as Blacktrack, which I like for certain looks. I wouldn't get Blacktrack if I were you because you can simply put say, Carbon on top of BnG and viola! Blacktrack.

I have both and I dont really use Blitz and Glitz. I love Blacktrack because I love to wear intense black eyeliner like Arabic style!!

I only got Blitz and glitz because it has gold in it & my fav colour is gold. But it's not so bold, more of a subtle black for a softer look.
