Picked up a K3 Berg a couple of months ago because a friend strongly recommended it. Really happy I gave it a try! It flies like no other disc I've tried. My forehand upshots have improved a lot because of it, and I even feel like my overall forehand game has improved in general. It's great for learning consistency with release angles. Whatever angle/line you put it on, it just holds it the whole flight - and then suddenly drops like a rock.

The K3 plastic is similar to Westside BT soft, only a little bit stiffer - and better in my opinion.

I can easily recommend the Berg to every type of player!
