It doesn't get that cold in Texas, but the soft x-link is nice in the woods when you want the disc to drop and not bounce out in the woods... or approach and not roll down a hill.
On another note: I noticed that I haven't been throwing the Ridge very much lately. When I want fade or forehand approach... VP. Long putts... VP. Long approaches... Summit. Putting in the circle... Summit.
There are times when I pull out my Ridge and sometimes I throw the Sole, but it's "maybe" one time per round each. As great as these discs are, I don't know how much longer they'll be in the bag.
