Combination knitter here, all the way. I hold the yarn the typical Continental way and do almost all my knitting combination style. The purl is sooooo much easier/smoother for me this way and my stockinette comes out beautifully. No rowing out or uneveness.
When I'm following a pattern I just adjust stitches like someone else mentioned...like it the pattern says "k tbl" I'll knit it through the front. It's really helped me learn to read my knitting because I pay attention to how a stitch is sitting and how it should sit when I'm finished with it so I can adjust increases/decreases, etc etc.
If I can't figure out how to alter a stitch in my head for combination style, I just reposition that stitch to continental/english orientation when I get to it and knit as written in the pattern.
I was quite happy when I discovered it
Hooray for Grumperina and this site.
