The complete rub pack provides a number of different rubs for different applications I have tried so far.
SPG is great for traditional Texan brisket or Californian tritip (very similar to the original Santa Maria rub)
The Chud Rub is an universal rub which I have used successfully for pork ribs and chicken thighs
Sweet cheeks works well with chicken.
Snake bit is for myself more an add on or round out rub. The combination with Sweet Cheeks worked well.
Highly recommended
