This is a great disc. Stop and drop flight. No glide. Unusual rim shape is not a factor as a thrower but not so good as a straight up putter with my grip. I also purchased a Berg in K1 which has gone straight into my bag as an approach shot / give it a run disc. Slight over stability makes it perfect for nose up stall approaches. Lack of glide can be a limiting factor so knowing your range is important with this disc. Within range its great.
Only gets 3 stars in the K1 Soft as this plastic is way to tacky for my liking. Can feel it sticking to my palm when releasing. May get more use in the winter / colder days. K1 plastic is a 5 Star.
