Rollers for days. Flips if you so much as look at the disc. Easy hyzer flips and turnovers for beginners, probably unusable for anybody in the 350+ range. I'd only suggest this disc if you need a scramble disc that you need to throw vertical in the woods through tight gaps and get to stand up all the way to flat.

Underworld is a great first driver for someone looking to move into the world of drivers. For an intermediate player it is a hyzer flip machine that is great for wooded holes. For me this disc flips up to flat and flies straight for a long ways thanks to the 6 glide. This disc has a ton of glide and really likes to stay in the air. This will help beginners get more distance out of it too. Being a 7 speed it is pretty easy to control too since you won't have to throw it as hard to get good distance out of it. Once it gets beat up it makes a good roller disc. The stamp is really cool too. 

Disc up, power down for the tight tunnel shot w/ the underworld. Ridiculous glide! Super straight when thrown with the correct arm speed on an extreme hyzer. 

if you drive forehand and are looking for a fairway driver that’ll flip and hold the turn, stop looking because the disc is right here. The Underworld I initially bought was much more stable than I thought it would be out of the box, but two good tree hits later it matched its numbers pretty well. This is the only disc I grab now when I need to flip something and have it hold the turn line. That said, if there’s any noticeable headwind, this is staying firmly in the bag. 

This disc is super understable, which is a good thing once you figure out how much hyzer you have to put on it.  That being said once you put it on a hyzer, this disc will hyzer flip to flat and then fade back left giving the begginer some distance or it can be muscled and forced to turn over into an anhyzer/ or anhyzer-flex when you need it to.  FYI: When I first got an one of these, I sadly couldn't get it to do anything other than anhyzer into the dirt because I was throwing it flat, so if that is the case, I suggest you get out and do some field work and get this baby to hyzerflip and then put some pepper on it and forcing it to turn over to the right, when thrown backhand.  Not a recommended headwind disc though, too flippy to be reliable.
