Yeah, same diameter as a Pig, but shallower with a narrower rim and very blunt, so almost lid-like possibly. I think the super wide rim is one of the defining features of the Pig that gives it the feel it has for driving (and also what makes it truly a mid, not a putter). Being shallower with a narrower rim and much blunter, I doubt this disc is going to replace the Pig. Even if it did, I think the Innova Factory store would probably continue selling their stiff pro Pigs, which are the only Pigs I buy anyway.
If you're looking for similar discs, the Harp, Zone, and VP all actually have similar rim configs (around 65, so not quite as high as this but much higher than the Pig). The Zone also matches the depth and rim thickness exactly. So this could also be a premium plastic driving putter to rival the most OS putters on the market (more OS than a Pig and with more skip).
