But i think the disc that disappointed me most was the 165g Star Valkyrie I bought that was just a glideless, overstable brick. I did the hot water treatments, threw it into a brick wall many times, and tried to use it for months to wear it in. No luck; it might as well have been a Firebird. It's still as bad now, even though my own form has improved a lot over time.
Just started into this thread. Your post reminded me of a Sidewinder that a dgcr friend has. I think it's a star. He uses it in the same slot he throws an Orc for. From -3/1 as advertised to -1/3 flight. However, he likes the disc for what it is. It's just not what he was initially looking for. Could you use that Valk in a fb type slot?
As far as my least favorite disc. I got a Franklin set at Ollies when I first started. Even then I knew something wasn't right. I think that they were made of melamine. :gross:
