after you roll the paint on you run the brush over the trim with the tip of the brushThey don't hold paint well. I like the brushless look. I don't know what you mean by tipping the brush.
The mohair rollers are ok they are best for oil base. It's hard to find a decent short nap roller, most of them are too long of a nap. I never use foam rollers they're stupid.Have you guys ever tried the mohair roller covers? I prefer those over foam rollers
