I'd felt similarly about the Monarch before, but from a couple recommendations from friends, I got one of the CFR Star Monarchs with some scrip at the Fernburner. The champ Monarch I found to really fly when you threw it just right, but it was really touchy--either ended up too stable or not enough. The star, for whatever reason, seems to perform much more consistently. I was throwing it yesterday a bunch, and the issue I kept having was that I kept throwing it too long and too straight.
As for the worst discs by the big 2...hmm. I never really liked the Skeeter, though it's probably not a bad beginner disc. And though I've never thrown a Spectra, I'm not sure if I've ever heard anyone say a positive thing about them. The Buzzz GT is pretty worthless too, IMO.
