You'll want to try the Claymore for tunnel shots. It's a tad more stable than the Fuse and the glide is excellent.
I'm not so sure about this. At my trilogy challenge everyone (myself included) found the claymore to be fairly US. I could definitely see it as a good tunnel shot disc on a hyzer flip as it has so little fade and will be straight if flipped up, but he wanted something that will hold straight in a headwind which I don't see with the claymore.
