I got this as a mystery disc a little while back. I'd say I'm a pretty consistent 350-375ft thrower, literally the first throw I ripped a 427ft foot throw! Loved it to pieces, it would just glide for days with a beautiful s-curve. Unfortunately I lost that disc, it was the 400G plastic. I decided to reorder it and try the 750G plastic, wish I stuck with the 400G. The 750G plastic seems to be much more overstable than 400G. Could just be the disc but I'm not enjoying this one as much as I did the other one. Either way I know its not the disc but for the way I throw the 400G seems to be a better fit. Still, this disc is one that I keep in the bag and will probably always have. 

The D1 is an interesting disc in the same vein that the different plastics can fit almost every driver slot in your bag from long turning shots to extremely overstable.

The feel of the D1 in hand is really what drives it home for me. It has a fairly wide rim, but it's not uncomfortably wide. It fits nice in the hand and allows me to get a consistent release out of the disc everytime I throw it.

The stability is a bit of a whacky spot for D1's, but that's not a bad thing. Having a driver that can cover every range of stabilities is generally looked for in player's due to the same feel in the hand (much like Innova Destroyer stabilities).

Overall, the D1 is my favorite driver in the Prodigy line up and believe that it works best for higher arm speeds, but can find a utility slot in lower arm speeds.

When you go play a 3 disc challenge with your buddies, this is the driver you bring. Its OS but not SUPER OS. The 750G plastic is amazing. Great grip and just the right amount of flexibility.

My main driver! Alot straighter then I imagined and goes a mile!! Confident rips in all conditions.

If you have 400+ feet of power and looking for a driver you can mash on without fear of it turning and burning, look no further.  750G flies exactly to the numbers, which is what makes the 750/750G plastic so great.  It takes a long while to beat in so you have a reliable disc for a very long time.  Just like 400G, beginners that haven't gotten comfortable throwing flat will struggle with this disc. One difference between the 400G and 750G is the dome. There is a nice amount of dome that comes with 750G that many 400G don't have which means these are going to have more glide and more carry.
