I bag the knight stamp CG FD3s that start a little less stable then the Innova made C-Line versions. I only have 1 backup left and would like to find a good replacement that isn't reseller priced if I can. I had a bag full of Innova made Discmania and tried most of the in house stuff but don't care for most of their inhouse/ HOD reproductions. I tried the MF FD3s when they dropped and they are ok but not the same. The only thing that has stuck around is the MD1.
I thought the Scepter might be the FD3 because of the way the profile looks. Judging by what Infinite is showing on their site for profiles I wouldn't really call them truly flat. Profile mostly looks very similar to my Innova made C Line FD3s. Might try one of the lighter swirly star Scepters and see how they work.
