I have 5 Diamonds. I have only been playing 3 months, and I barely get over 200 feet (normal is 175-200 feet). Leopards were my best disc, but now if I throw hard, they dive right, and often flip into rollers. I think the dive right, turn into rollers can be a symptom of throwing too fast, but just as easily is a combination of bad form with trying to throw it hard/fast. My Diamonds like to go straight, or gentle S curve. They almost seem to help correct my errors in form! If I improve my form, a lot, Leopards can go 250-300 feet (really good players can do that). I started getting them 150-175 feet regularly, then as I tried going further, started getting right dives and flips into rollers. Now I carry a Leopard for an approach shot that is too long for my putter, but not so long that I need my Diamond. Sounds like you are at the same spot with Diamonds that I am at with Leopards. Throw that Diamond slower, and/or with better form, and you will grow to love it! 200 feet straight and accurate should be easy for you with the Diamond - just slow down your throw, and keep it smooth. Diamond is a great beginner disc for distance - you know, guys that still suck, like me.
