Fun topic.
The Tangent and the Crave are the two MVP/Axiom discs that are perfect for my game. The Crave in particular ended a months long search for a straight flying disc disc with strong HSS that's still workable on a variety of lines. It's exactly what I want for that slot and I throw it more and more and more. The Tangent is the perfect stable to mildly understable disc for me. Truth be told I don't know it as well as I'd like to: the lack of tight course coupled with the strong winds in my area means I don't throw them as much as I do when playing up north in tight, wooded courses. Still, they've saved my butt countless times; some of my most memorable shots have been with a Tangent.
I'm bagging the Tesla and Resistor as well. The former is pretty new to the bag: I love it for hyzer lines and love its speed - fast but controllable - but am still not sure how solidified it is in the bag long term. The Resistor is a great great disc: it's my crutch in a lot of situations, since it's so absurdly reliable. The Resistor is close to the "lock down" status of the Tangent and Crave, but not quite there.
The MVP discs I haven't clicked with that I've spent some quality time throwing are the Tensor, Inertia, Anode, and Servo. The Tensor always flew weird to me: the HSS is there, but it's also quite sensitive to release angle, and I had many throws with it where it held onto a flat or slight anny release way longer than I wanted it to. The control is outstanding, but I couldn't dial it in even after a lot of time with it. It only took a few throws with the Suspect to convince me that the Tensor wasn't right for me. The Inertia is just more understable than I need, plain and simple, at least right now, and the Anode was just meh for me. The Servo had way more turn than I wanted: a great Eagle X-type line shaper, but not something I need in the bag right now. Lately I've preferred the tighter lines of discs like the Crave, Suspect, and Tangent.
I've thrown some other MVP discs, but not enough or too long ago to really have an opinion on them. The Shock bears mention as a disc that seems to do exactly what it was built for, really really well, but I don't feel like I need one in the bag given the Resistor's entrenchment.
MVP/Axiom have a great, intriguing line up that has filled out really well.
