Re "The days of the salchow & loop are over," maybe, maybe not. These things change and shift depending on the table of base values. At one point, the throw flip was the same value as the throw loop. Now they are different, and have been for some time. However, it seems that teams learn the throw flip/lutz if anything, easier than the throw loop, which is why some teams don't do the throw loop, even though the throw salchow has a slightly lower base value. It's entirely possible they will go back to the same value some day. Not to mention that the throw 3A is grossly undervalued, and that may change some day. In the case of the teams doing SBS flips or lutzes, considering many guys lip and many girls flutz (and a few the reverse), I don't think these are ever going to be universally done, provided that the pairs tech panels do their jobs on edge calls. An edge call wipes out the advantage of the higher base value jump. Certainly, I don't see a whole raft of teams that you could put together who would do the 3F in one jump pass and the 3Lz in the other. Not to mention that a girl who can do both a flip and lutz (one in combination) clearnly is likely to be continuing on in singles. Yamaguchi & Galino in the early 1990's were doing side by side triple flips-it has never caught on generally in pairs.
