Not sure which run these are from, but they are all almost entirely clear and very grippy. OAT isn't making these turn over. The 167 and 168 turn from flat at 375' of power (167 more-so than the 168), yet they are pretty straight for understable drivers. They are amazing discs for open distance, but they tend to float around too long and don't fade enough to be reliable on distance shots that need good placement. The 175 has no glide and doesn't turn or fade much if kept low...It drops quick enough before the fade will kick in. Yet even still it moves around in the wind too much. I'm not so sure that it will have a spot in the bag much longer, which is why I want a more stable compliment that will handle winds and still be workable.
And when these were new they didn't turn much at all. Lightly sanding the flash and giving them a good run through a rocky, wooded course helped get them where they are pretty quick.
If it helps, here's some PLH comparisons.
