I found optimal algs for all PLLs in HTM, ignoring initial "AUF's" (Macky's term: adjust-U-face).
Of course, it was no work: just feed them into Kociemba's program.
I haven't seen a list of these before (there was a question about this, http://twistypuzzles.com/forum/viewtopic.php?t=6512
, but I think that concerned execution), so I typed them up.
I found two algs particularly noteworthy:
Y: F2' U F2' U F2 U' R' U' R F2 R' U R
E(?): L U' R D2 R' U L' R U' L D2 L' U R'
