I love this disc!! It is my go to for almost every drive. It's slightly under stable but has quite a bit of fade. I highly recommend you add one or two to your bag. I never play without it. Very beginner friendly.

My Neutron Rhythm is flat and quite OS. Thrown on a flat angle with good power it stays mostly straight throughout its high speed flight then slows down and has a pronounced and strong fade. From hyzer angle it will hold the line the whole way making for nice long sweeping hyzers. It does well on anny lines that flex back at the end as well. Its pretty low glide, so it needs good power to get decent distance. Its a good disc, just not at all what it is advertised to be. I've seen others that are not as flat topped as mine, I bet those are more true to MVP's flight numbers.

So I likely got a unique one as it's super flat and has a kinda high PLH wing. 
mine only has turn at high speeds then a pretty sharp hyzer. 
Mine is not a smooth super straight disc. This one shapes well. Has some decent turn with strong throw  then hyzer back kinda hard late. Still skips. On hyzer it flips flat for a moment then is a bit OS.

I call mine 7.5/4/-1.5/2

From what I've seen most others are pretty flippy. 
mine is funny. But I'll make good use of it shaping through woods. 
 

i don’t know why but mvp fairways kinda suck. Other than the volt. The volt rules. My favorite fairway. All the others like crave. Signal. Clash. Etc. I tried a lot of them. Don't love em. Thin rims and mostly thin flat profiles make them touchy. Relay is decent. Volt rules. Rhythm. It's ok. Maybe I'll check out a newer run and see. But I'm happy with all the other fairways I own. 

Actually thought this would fly alot like my Squall, just a speed up, but I was shocked how understable it is. If thrown flat, it will flip over most of the time and cause it to lose the glide . I was surpirsed how consistant it is at hyzer flip up though. I would recommend this disc for someone learning how to hyzer flip. 

Love this disc. I didnt purchase from here, but have been looking for a leopard replacement that doesnt burn over for me.

Put on anhyzer and it will turn nicely without burning over and a little fade at the end

Flat you get a nice S turn

Hyzer nice a straight (with maybe slight turn) with baby fade

I have seen it compared to the Crave... this is not the Crave. If I put a crave on any anhyzer it keeps its turns. This filled exactly a slot I needed between my Crave and Insanity. This is my got to disc for most of my shots. 

I really like this disc, though the one I got has less turn and more fade than the numbers suggest. It's  more OS than my Crave.

I tried the circut challenge one during the event (173) and bought a neutron one (172). Not really that. Both flew much more straight, baby turn, and faded at the end for about 275 feet or so. Not a lot of glide. I've had a few people with more power than me throw it and saw similar flights. Maybe I got two stable ones. I know many people suggets getting lighter weights for gyro discs to better approximate the flight numbers,  perhaps that would help.
It's not bad, just not what I was expecting. I thought it'd be more like an F5/Leopard3. Seems to be more like a fresh essence with less glide.Hand feels is nice, very flat and comfortable for forehand/backhand.

MVP / Axiom nailed it with this disc! Wow what a home run!

This has become my go to driver when I need reliable laser straight precision. I have a low power arm and for my RHBH throws it flys perfectly straight for about 200ft with and very light and predictable fade to the left finishing around 225ft. After a month of playing this disc 5 days a week I decided I would be heartbroken to lose or have it discontinued on me (like what happened to my favorite axiom midrange) so I went and bought two more just in case. 

This review is for the stock run Rhythm and not the 22 Circuit Challenge run which flew more overstable to me.

The Rhythm is everything the MVP Relay should be if it were more consistent (tends to be a lot more overstable). Great hand feel, releases clean, slight natural dome, and as always MVP plastics are top tier. I find the flight of the Rhythm to be spot on with with the numbers but flies WAY further than any 7 speed should be going. Thrown flat it'll drift the entire flight and ever so slightly fade at the end. I find this discs shines most on a hyzer release on the right amount of hyzer the Rhythm flips very quickly and just locks into a dead straight flight and goes forever before gently fading to the ground. This is my go to tunnel shot fairway or flat to turnover disc. Great, great disc.

If you're looking for a disc to learn how to hyzer-flip, don't look any further; this is the one.

I have a neutron rythm that I got form the MVP circuit challenge in 2022. This disc immediately found a spot in my bag. If I back off and throw it at less than full power it has just enough turn to keep the disc from fading out and it goes perfectly straight until the end. I use it for hitting longer gaps in the woods or ceiling shots. The discs flight characteristics are similar to an Innova leapard3 but with a a flatter top. I can see this being a good disc for beginners learning to hyzer flips discs.
