I am a fan of these D1's. They are flippy, but have a nice OS flight.
Not as OS as I'd hoped for, but its still a nice straight flying disc with some hook at the end.
Ordered 2 of these, both look and feel great; not the swirliest spectrum run, but awesome colors and nice, grippy plastic.
The swirls are awesome on the 400 Spectrum and makes each disc a one of a kind. If you’re looking for an OS driver, this is likely not the disc you’re looking for. Feels okay in the hand and has a nice small dome but expect a straight flight will a small fade. Awesome looking disc and has found a spot in my bag.
