Any opinions on these sires

[Nijinsky]

Since no one commented on my post concerning these new sires I made a new one. Spinelessjellyfish has a stupid name but he shares the same sire as leading California sire Bertrando. I like the fact he was sound.
Richly Blended wasn't sound but boy could he run !
Any comments ?

My ONLY unproven sire picks would be these five new sires.

Spinelessjellyfish comes from a tough, tough South American family, which is probably where a lot of that soundness comes from. The Missy Baba, Lalun, and Foggy Note close up in his pedigree add some nice choices to linebreed to, through stallions such as AP Indy, Rubiano, Tabasco Cat, Smokester, and Glitterman. The South African branch of this family has a Gr-1 winner by a son of Fairy King.

Siphon mares might also be an interesting cross with Spinelessjellyfish, returning the blood of the top South American stallion Tatan (Arg) and a pair of strains of Tourbillon (Ambiorix and Fort Napoleon).
