I like the Photon a lot, a very good undersized. It is nominally a bimetal, but it’s more of a style thing really. Anyway I can recommend it!
What about the M1?
The M1, at 35mm wide, is narrower than I’m looking for.
I know it’s been a bit, but I bet you’d like the Dietz. It’s a competition based undersized throw.
I played @TheThrowingGnome’s at our GA meetup, and had to have one!
I traded @Grendel for one a couple of weeks ago, and I’ve been pretty obsessed with it.
I can only vouch for the Y-Factor. It’s a little unstable and unforgiving for a newer player but it’s a fun, light throw. If thumb grinds are your thing, this has a lip. Has mid walls which help with rejections.
YO. I can’t believe I forgot about the Dietz. Probably my favorite undersized OD I’ve had. It actually is quite stable for its size too.
