This is a very good driving putter. I picked up a zero-hard Sinus after watching nikko throw it. It handles power very well, and can become a point-and-shoot putter once beaten-in. The disc does not turn over unless you put it on anhyzer angle, but will still flip-up to flat when powered on. This is great for tight 200-250 foot straight shots.

The disc is not overly deep, either. I have large hands, but don't necessarily like throwing discs as deep as a bathtub. The Sinus allows for confident, full grip without feeling like it will get caught on release.

The only complaint I have is the sharp lower ridge on the bottom of the rim. This may feel uncomfortable at first, but once it beats in, this is less of a problem.

This is my main go to Putter. Zero Medium. For putting, off the tee, and upshots. I love the Sinus.

Like others have stated, the grip pads on the top aren't for everyone. But they are spaced apart so that you don't have to use them if you don't want to. The lip underneath is deeper than most putters, and a little on the "sharper" side. But after the disc gets broken in, the "sharpness" will wear in and no longer be noticeable.

What I like most about this putter is that I can put all my power into it and it may turn over just a little bit, but more often than not, it won't turn over at all. It flies dead straight with a nice little fade at the end. This disc is a brick. You wont get much glide out of it. But you also wont get the big skip at the end. It pretty much just sticks where it lands. Also holds up well in a headwind. Not as well as a Harp would, which is what i use only on really windy days.

So, if you're looking for a putter that wont flip over when used off the tee, or on upshots. And do not want that big fade at the end like a Harp, the Sinus is your disc.

The Sinus is a putt and approach disc from Latitude 64. The Sinus has a lower profile and fits comfortable in the hand, but it has these grip strips on the disc for added grip. These strips just annoyed me more than anything, the Zero Soft plastic was plenty grippy without the strips. The plastic was grippy, but a little too soft for my taste, it almost feels like a cheap kids toy. The flight of the Sinus has some stability and I would compare it to a new KC Aviar. It is straight, but has a nice fade at the end of the flight. It worked in the circle on shorter putts, but I didn't like it outside the circle, it was a little stable for me. It really worked well off the tee and on approach shots, where that fade makes it easy to dial in the accuracy. This disc does not have much glide at all. I like the flight, just not the feel of the Sinus. 

The only disc I will approach with, outside of putting range but inside of a midrange shot (60-200 ft for me).  I bag an AP Sinus and a Soft Sinus.  AP has enough finish to it where I can get a good skip out of it in short to medium length grass, and the soft pretty well sticks to wherever it lands.  They are fairly overstable, but do hold a nice straight line for 70-80% of the flight before finishing, and when in new condition, both resisted turning over effectively. As my soft has broken in, I have found I can get the disc to flex when thrown flat, and almost completely hold an anhyzer line with enough put into it, making this disc versatile on a whole new level for me!

The feel of the disc is perfect, and I really enjoy and use the thumb pads on all shots.  I only tend to use the most coarse pad, however, as that provides the right amount of added grip for me, and is most comfortable. 

Sinus is an amazing disc that I think everyone should throw one at least once!

The sinus is one of my favourite discs. It is my go to disc for almost all my upshots. i love the consistent flight and the soft plastic sits were it hits. This disc is a must in everyones bag!
