I only have problems with it splitting if I drop and wind the yarn around my fingers a lot. You can usually see the yarn starting to twist around itself. I just spin my project (or skein if it's too big) around until it isn't as twisted anymore and it works better.
I think it does work better for crocheting. I don't have to wind/unwind it around my fingers as much so it doesn't untwist/unply itself.
