A follow up question I’d have is if you’re playing scales just because we’ve always heard all musicians should play them (
) or if they actually occur in music you’re currently playing (or want to play). Many great players don’t play scales. If you start right at 25 minutes here, Troy and Albert talk about scales a little:
He sort of reluctantly admits that he, in the context of a song, wouldn’t really play a scale. And they “straight scales” he demonstrates sound very sterile compared to his typical smooth sounding more cascading phrases. Also some fun CTC data is that at 26:28 Troy actually uses the phrase “falls apart”, which is hilarious since I’ve seen many forum posts where he says how much he hates that phrase lol! Fair point, the phrase doesn’t tell us why the thing was bad (more “clunker” notes appear, hand sync degrades, tempo starts to drag etc). Still funny he used it himself. Maybe that’s before it developed that “trigger” for him lol 
But I digress
Other than some classical pieces that do have complete scales in them, usually in more mainstream music, we don’t see straight scales. We get fragments that move sequentially, or change contour, or have chromatic passing tones, or briefly go into an arpeggio etc.
That’s my non-answer
Even if you play scalar-type lines but they aren’t straight scales, or if the above doesn’t apply because you have a legit reason to need to play straight scales (OR you just really really want to and you enjoy scales), you’d still need to have a good fingering choice down. For me, I’m comfortable with the tried and true 3NPS just because I’ve been playing them as long as I can remember.
Something most people haven’t tried (including me lol!) is the Segovia scales.
More position shifts than I like but it’s an option. They aren’t DSX out of the box, but you can of course mitigate that with strategic hammers/pulls. Who knows, it might spur you to create some interesting lines since it’s likely a departure from how most of us play scales. I’ll add that to my never ending list of “things to try when I get the time”. Spoiler alert…I never seem to find the time. Maybe if I didn’t write such long forum posts…
