Irina Slutskaya did 3S+3Lo, 3T+3T, 3Lz+3Lo.
Elena Sokolova has done the elusive 3Lo+3T
. She also did 3Lz+3T in 2003 and I think I remember but can't find video evidence of her doing 3S+3T and 3T+3T+2Lo at least once each.
How about combos with half loop between two triples? E.g., Tara Lipinski did 3S+3Lo, 3Lo+3Lo, and 3T+1Lo+3S.
Surya Bonaly has done 3F+3T, 3T+3T, and 3T+1Lo+3S. I think she has also done 3Lz+3T, but I can't quickly find confirmation.
Sorry, my brain got full during the 6.0 era and I haven't memorized as much from more recently.

(Actually it's probably more that I have access to so much more skating online now that I don't watch the same programs over and over any more.)
