Right Hand Improvisation Fingering

[etalent]

I'm loving Jamey Aebersold's improvisation exercises, where you play along to a backing track, holding a whole or half note chord loosely with the left hand while concentrating especially on playing improvised melodies with the right.

You play seven "exercises" or portions of a scale with the right hand, while the left is just harmonizing loosely:
(1) first 5 notes of scale,
(2) full scale to the 9th,
(3) root, 3rd, 5th,
(4) root, 3rd, 5th, 7th,
(5) root, 3rd, 5th, 7th, 9th,
(6) same as #5 ascending/scale descending,
(7) opposite of #6.

My question is this: what should the fingering be for the right hand? For #1, #2, and #3 it's simple enough, but things don't happen as naturally with the rest (#4, #5, #6, #7).

I strive to practice scales with strict discipline on correct fingering especially before I try the exercies I'm describing here, but that fingering doesn't fit.

What do you do? Do you just let the fingers fall where they will? Please suggest away.

Thanks,

#4. 1234
#5. 12345 (fast)...or 12312 (for smaller hands)
#6. 1234543214321 (fast)...or 1231214321321 (small hands)
#7. im not sure what u mean

of course im assuming that these are all in the key of c maj...otherwise the fingerings would change considerably

whatever u do....don't just let your fingers "fall where they will"...it will lead 2 a zillion problems later
