Got my Sinus AP in the mail today from Disc Golf Store (shipped Tuesday, arrived today) and took it to the field. Love it so far. It has a similar feel in hand to a Pure, with the shoulder being a touch taller, and the Zero plastic is super grippy.
If people call the Pure a mini Buzzz, I call the Sinus a mini Pain: straight with a strong, reliable fade when thrown flat; fights back out of an anny; holds a hyzer. I can already tell it is going to make the bag, because it seems really dependable. Also, it laughs at the wind.
If this thing were in Opto, it would be pure beef. Time to send a message to Latitude...
