Finally had a chance to throw my new 164g Halo in a field today. But it's not an "all things being equal" situation, because I'm also trying a new grip for the new year. Previously, I was using a three-fingered grip, where my pinky was out of the equation. But the left side of the end of my index finger gets thrashed badly if I play too much disc golf, so I decided I'd better experiment with something new. So I squeezed all four fingers on the underside of the flight plate (some kind of "Power Grip," I guess), let loose a couple of test throws with my Surge, and... added 25 feet to my drives. :shock: And this with a cold arm that hasn't thrown a disc in two weeks. I threw one 330' on a slight (4'?) uphill and 390' on a slight downhill.
Then I tried the Halo, and was basically getting the same distance as with the Surge. A little less flip and a little bit harder fade, but wow, such a beautiful flat flight. One lucky Halo shot went 415ish with maybe 6-8' of downhill slope.
But, here's the thing: I love love LOVE the shallow rim on the Halo. I don't have huge hands, and including my pinky in the grip was a little awkward with the Surge. With the Halo, it felt very natural. (Reminds me a lot of a Flick, actually.) Props to Lat64 for the shallow rim and the light weights!
