(Also is it in bad taste to post two questions quickly consecutively?

No, not at all.  Besides, you're Scott Pilgrim, so getting with Mary Elizabeth Winstead means you pretty much rule.

Yeah, my LH is still comparatively weak at doing intricate scalar work.  It's extremely strong in a lot of other respects, but scalar passages:  that's what slows me down, chops wise.  Good enough for most repertoire I deal with, but not perfect, and still not equal to the RH in terms of speed at intricate pattern-work.

The only thing that's been giving me consistent (although slow) results is a combination of repertoire work which features the LH (either alone or in combination with the RH in unison or at various intervals) and simply executing scales for the LH alone or with the RH.

Or fragments of scales, or even melodies:  like, say, taking a 32-bar standard melody at very fast tempo, and putting it entirely into the LH or making a game of it by alternating the melody between hands.  For me, that's jazz tunes, but it could be something else.  I like "Donna Lee" starting in Ab and transposing up and down, tunes like "Parisian Thoroughfare," any and all "rhythm changes" tunes in Bb, and improvising at the octave HT, or just LH solo. 

Could be any melody, though:  those are just ones I like personally.

This presumes knowing the absolute best fingerings, adapted for your own hand, which is also going to vary depending on the patterns one is executing.

There are certainly some specific pieces of repertoire or even melodies that I favor for this ongoing challenge, but it's a really wide range of pieces that will challenge you, so, I'd say you could make your choice:  it's really a fundamentals type of question which can be adapted to what you're playing at the moment.

As for exercises written out?  There are quite a few good ones in various bits from Czerny, but they're really just echoes from moments in Beethoven.

You could try the Moszkowski G minor étude if you like:  it's pretty musical, and certainly will give you something to practice.  About as difficult as the Chopin "Revolutionary," except it doesn't drone on forever and ever.  IMHO.

I personally have preferred to isolate the technical or mechanical aspect, and incorporate any results into a revolving door of pieces from repertoire or even just improvisation, but that's really down to how you prefer to work.

And I did develop a tendon problem (since healed) by overdoing it with the G major Chopin prélude by forcing myself into a technique which wasn't correct for me, so you should probably avoid strain at all costs:  that's the main reason I'd insist on looking very objectively at your technique while deciding the correct approach, and not be mesmerized by the flashy appearances of various pieces and the temptation to play a given piece at full tempo (that is, making it sound "good" and perhaps fluffing over some details with the pedal) without having the correct mechanics isolated and mastered.

Not that the Chopin prélude is especially difficult, but there are a few uncommon adaptations one must make for the LH, played as quickly as possible, without pedal, except maybe a light "splash" on each downbeat of the bar to assist with the RH melody ringing out, and for overall effect.

/* That said, I don't know exactly what aspects of your LH needs work:  for all I know, you may be struggling with wide leaps, and not scalar passages, or need help making larger intervals playable for your hand, which can also be addressed, but in slightly different ways. */
