You can think of it anyway you like, but if you don’t know what actual joint motions you’re using for the “two slants”, you won’t really know what you’re doing, or how to make it better. When you switch the “slant”, are you switching to a different picking motion? Because that’s what “2wps” players like Andy Wood appear to do, even if it’s just a slightly different kind of wrist motion. If you’re not sure, it could be that’s why you find the switching to be weird.
Even still, pentatonic licks are mostly one-way pickslanting licks anyway. The Eric Johnson fives pattern, for example, only works with an upstroke escape picking motion, and only has two notes on a string. I’m not even sure how you would make that into a “2wps” phrase even if you wanted to.
Edit: If you’re a wrist player, another thing you can do is check out the new wrist motion section in the Pickslanting Primer. It is the simplest presentation of this stuff we have done so far. We haven’t added the chapters about switching between motions yet, but when we do, the foundations for this are outlined in the stuff we have up there now. The nice thing is, the two basic motions we’re looking at there are all done with the same arm position. So when you get to the point where you’re playing phrases that require both, there is almost no real change to your setup necessary to do it. And any changes you do need to make will be minor.
