I've been meaning to buy a Berg K3 for ages as it immediately felt good in my hand. Still learning the disk, but it seems to fly wherever you aim it (hyzer, straight, ani) and then stops like a brick as soon as it runs out of power, without gliding past. I wouldn't particularly recommend it for putting, as I get a weird release due to the unusual shape, but it's a great approach disc. Hyzer flip on low/medium power gives a nice straight flight, with a little turn or fade depending on the power. I'm experimenting with full power hyzer flips and it seems like a really straight flyer even at speed!
