What's wrong with 7018 for everything?
Just a couple welders and a couple of big hammers and torches.

these videos are worth a watch.
edit: I know you have to do restarts properly to avoid slag inclusion. I think all three videos go over restarts.
3G 6010 root 7018 fill/ cap

As suggested by others, ditch the 6013 on the root. You can use the 7018 100%, or if you feel you really must, use a 6010 for your root - it is what it was made for! I would ditch the 6013; I am not a fan of the 6013.
What are you doing for manipulation? If you are doing any of the 'little circles' or 'ovals' or 'lower case "e" shapes', you might be in trouble. Doing those wrong can lead to lots of problems. If you are doing some kind of a 'Z' weave, and you are 'stepping' too much - weaving too wide, that can lead to problems.
From what you desctibe, beginnings and restarts, you might not be allowing the rod and metal enough time to heat before you jump in with your weld. Bring your rod down slowly, allowing the rod to do a bit of preheat, which will allow the rod to get hot and the arc to stabilize. Longer arc equals more heat, and maybe that is what you need
