So, I have 5 light weight DX Mambas. One of them is 147g, and I throw it well 3/4 of the time. I throw it on a hyzer angle, it flips up to flat, and generally goes about 225-245 feet fairly straight, with a gentle fade at the end. The other four, weights 132, 145, 146, and 146, are very inconsistent. I try to throw them on the same hyzer angle, but they will often flip up to flat, then keep flipping over into rollers, and just as often fail to flip up, and fade hard left. When they do flip up to flat and go straight, they don't get nearly the pretty flight and distance the 147g disc gets. Not a one time thing - same pattern for several field sessions now. I am going to bag the 147g as one of my primary distance discs, while the other four - getting so I hate to even throw them in practice right now! Mambas or me, and how or why??? Thanks for any input!
