This plastic is great. It's a little grippier than the K1 Falk I carry. It's also more stable out of the bag. It is as straight a flyer as any I have in my bag, and I've tried a lot of different companies and plastic types. They are still a little pricey, but they are durable as heck, so no worries with them wearing out like some other plastics do. I play mainly on a mixed course that is about half desert. I can trust my Kastaplasts to stand up to the rocks, gravel, and cacti. The soft plastic seems to be even more durable than the standard K1 too.
