Scramble of the session:

Speedsolve / fast linear solve:

u2 U R r U R u2 (7)
R U2 B' R' B R2 U2 M2 U' r (10)
U' R U' L' U R' U' L (8)

41 STM. Pretty interesting FB, and neat SB (and fast CMLL too).


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Expanding it into FMC:

y2 z
u2 U R r U r U' u2 // FB (8)
R' U' r U' R2 U2 M' U' R' // SB (9)
U M U M2 U' M' U2 M2 // ignore CMLL, finish LSE (8)
alg.cubing.net

That leaves a skeleton with two twisted corners in 25 STM. Insertions:

y2 z
u2 U R r U r U' (L' U L D2 L' U' L D2) u2
R' U' r U' R2 U2 M' U' R'
U (U' R D2 R' U R D2 R') M U M2 U' M' U2 M2

With cancellations:
y2 z

r U' R2 U2 M' U'
D2 R' U R D2 r' U M2 U' M' U2 M2

31 STM / 35 HTM.

For the second block, I would use:

But that doesn't lead to such a nice LSE.

Just trial and error.
It took maybe 40min.

Interesting first block.

If I were doing your colors, I probably would have done
y x' R' U R2 U' // Square
D Rw D' Lw' // Pair

Results is a 46STM solve

Or, continuing with your solution, I found a slightly shorter LSE:
U' M' U' M' U' M U' M U' M' U2 M' U M2 U M2 (16)
But only 2 moves are saved, and I guess for our LSE fingertricks M' is preferred.
Nice tps though

I do aweful second blocks too... But that is aweful even for me.

Why not:
R2 U r U R U2 R U' R U R' U' r' M U r U2 r' U' R (20) ? To avoid a long CMLL?

But overall, I would use as SB:
r' U R' U r U R U2 R U' R U r' (13)

thanks. yeah, this solve is slightly longer than usual but my lookahead was great, second block and cmll were very fingertricky and there were no wasted moves. in a speedsolve I usually average low 50s stm.
