You're an FD thrower, right? How's the RGL Diamond compare to an S-FD?
They are similar in distance (The Diamond being slightly longer) and wind resistance, but as to flight, they aren't the same. My RGL Diamond definitely has a -3/4, 1 flight while the S-FD is more like a -1, 1 flight. I have an Opto Diamond that is nothing like that flight. Its more of a -1, 2. I can throw the FD on an anny and make it take much the same flight, but I won't. The Diamond takes way less work for a long anny and about 20-25% less power to get the same distance. The Diamond works great for right sweeps and the FD works great for laser beams with little fade. They work well together, IMO. Both seem to excel at worm burner shots. Very easy to keep low and long.
FWIW, all my Diamonds are max...159. My S-FD is a 166.
