I had this issue and got so pissed off I took all the braid off my baitcaster a while ago. Now I'm back on it but I did spool about halfway full with some cheap mono as backing. I have plenty of 30lb braid over it and don't have issues with it. As long as your drag is set right it shouldn't cause the line to dig in. If you ever see that happening make as long of a cast as you can and when you reel back in, pinch the line so it's going on the spool VERY TIGHT. That's the key.
