My own Point Black, as well as most of the testers at the counter I work all have quite a thick formula. I have not experienced a "pokey" brush, but what I do is carefully wipe the brush along the inner rim to get off excess, and sometimes wipe it off a little on the back of my hand so there's less product on the brush (with Cleanse Off Oil close to get it off my hand later). I have trouble with my Point Black because when I apply it I don't feel the brush. Like it's so smooth or something while I'm applying it I barely feel it if that makes any sense. I do like the Liquidlasts, but I do prefer Rimmel Professional Liquid Eyeliner.
Hope that helps!
