It seems that it depends from the motorization.
If you are running babymod or 13.5 blinky, you should go for Knack P-1001 (or 801) or TeamSaxo, and if you are running full mod, with or without timing, go for the VIP.
I've ran Team Saxo with 5.5, it is nice in the curves, but in the straight, it is quite dangerous
