I just received my 166, 170, and 174 Octanes. Threw them in a field yesterday. I have about 325-350' of power. The 174 had barely any turn, had a dumpy, "get to the ground in a hurry", steep angle fade. Something like -0.5 to -1 turn, 2 fade but hard fade. The 170 had some more turn, -1 to -1.5. The fade was less steep, more glidey. Because of the extra glide in the fade it was a wider fade, what I would normally call 3 fade. The 166 had great turn, -2 to -3 easy. Had the glidiest fade, and the widest fade. As much as it turned, even when I rounded one of the throws, it faded back just left of center. All 3 went the same distance consistently, just with very different flight paths. They were consistently landing in a neat line, with the 174 being 20' left of the 170, and the 166 being 20' right of the 170.
I totally messed up a forehand with the 166, and it went WAY left, but still hit a fade point and dumped into the ground. I didn't purposefully try any anhyzers but I imagine that even with the 166 that these would pull out towards the end because of this hard, choppy fade.
Thought I'd be trying the different weights to figure out which one I should bag, but I think I'm going to bag at least the 174 and 166. They all go the same distance interestingly, so the 170 just doesn't have a flight path I need, but the difference between the 174 and 166 flights is huge and the 166 has a very interesting flight to me.
