Which lipo saddles for my Yok BX?

[B4 Sloth]

What Lipos saddles are people using? Are the vampire/demon/intellect all the same?
What about the robbitronic ones?

I have 2 packs of trakpowers already and ideally wanted another set but they seem as rare hen teeth.

So, which should I buy? From a reputable shop only though!
