Do a sample with 22 sts, enough for 2 pattern repeats of 9 sts, and a couple edge sts. Try the pattern with both twist - one done their way and one done the other way, see if it does make a difference. It may be that since it's new to you and just awkward, and that by practicing it this way you might get the hang of it. Or you might find doing them without the k2tog looks alright too. I don't like how the k2tog R twist looks, it seems messier than knitting the sts separately.
sue- knitting heretic
