No idea on Blue Velvet, or Freight Train, but Send Helen's is St Helen's version of Air Ya Garn (nothing like it). Old Salty Dog has good flow, some cool boulder features, all easy with one step up that requires a bit of blue level skill. Be wary of the gap jump 2/3 of the way down, which is fine if you are carrying speed, which you will if you do the boulder feature just before it. Icarus has some fun tech, but very blue for a black run.
Can highly recommend Dreaming Pools loop, for a lovely xc outing, integrating great fast flow sections. We parked at the top of Lola Tier, then finished the loop with Garn Up. 35k's with 750m of climbing.
