As my bag has evolved to its current state, I'm starting to feel like MVP/Axiom is the Nissan of discs. And what I mean by that is that every time I have bought a vehicle, a Nissan has been under heavy consideration. I like Nissan's designs and combination of features and value. But whether I've bought a sedan, crossover, or minivan, Nissan was always the second place vehicle...meaning I bought something else.
I'm getting the same vibe from MVP. I really like their Photon/Wave/Vanish class of drivers quite a bit, but I get better results from just throwing Trespasses in multiple plastic types. The Vanish is still in the bag because I haven't beat in a Trespass yet to be that understable, but its days are numbered. Waves are purely backups now for my most beat Trespass.
I really like Envies and Proxies. But they are a little fast for me to dial in as approach discs, and I never clicked with baseline Envies for putting (probably because I prefer beaded putting putters). I still think the Envy is the greatest pure driving putter ever made, but I prefer the putter I drive with to be something that I am equally comfortable with inside of 200'.
So, much like most of my favorite vehicles that I didn't buy are Nissans, I've found that most of my favorite discs that I don't bag are gyro.
