Puffin is my pick based on your requirements and I do own all of them. It’s one of the faster CLYW throws, and it’s newer than most, which seems to have blessed it with the now-standard CLYW stillwater smoothness.
It also benefits from a mid sized diameter, which should be good for you, but it’s a bit wider than most mid size throws and I think that’s a performance advantage when I’m playing. I’m really liking this profile on the Puffin and Cascade.
The AC is also pretty good, and would probably suit you. It’s a fast, powerful throw where the Chief, and especially the Cliff, is a bit more leisurely. I find the Puffin to be much, much more stable than the AC though, so I would still recommend it first. I wouldn’t consider the Gnar as a competitor for these. Undersize throws are inherently a little less capable than their larger counterparts, I find (but of course can still be fun for their unique speedi-ness).
