This is what i would do in a speedsolve:
again, LSE seems so long...
and i can tseem to find "good" solutions for second block, as in, solution that are not totally cfop/zz-esque and require less moves

This solution is fully OK for a speedsolve.
For your LSE i have a 15 move solution, but this is a hard case.

thanks, but how do you know while solving which solution is better? (starting out with U or U') or is that just luck?

In this case it was luck, therfore your solution is OK.

I just realized there was actually a pretty good lse in my first solution, I thought the best one was 16, man I'm dumb sometimes. I really need to improve my lse.

Nice solution! Especially your F2L.

As LSE, I would do:

I suggest some SB alteratives:
U r M' U' r' U R2 U2 R' M' U' R (12)
or:
U' r U r2 U' R2 U2 R U' r' (10)

I discovered this SB accidentally: long, but leads to a very nice ending.

Thanks, I've been working on SB efficiency a lot lately. I would have posted that same solution first had I seen the good lse, I instead resorted to inserting the last pair with a sledgehammer which gave me the 8 move lse, but unfortunately added 5 moves to SB. It's really hard to find a good balance sometimes, I'm starting to think I should just do the blocks as optimally as I can and just put up with bad lse cases, it's always pretty fast no matter how long it is. Still working on cmll too, I'm learning the pi cases as we speak.
