You may decide that for your anhyzer and hyzerflip throws, you would use a mold in DX or R-Pro plastic.
You may then decide you need something you can throw flat or on a slight hyzer that will be a straight flyer and may choose a McPro Roc3 or KC Pro Roc.
For your stable choice, the Champion Roc3 would be your best bet. Now you may have one or more of these Rocs in the process of being seasoned just right so your mid range lineup may look like this: 2 DX Rocs (one well seasoned at 180 grams, and one newish one at 176 grams), 1 KC Pro Roc (180 grams newish), 1 McPro Roc3 (max weight slightly seasoned), and 1 Champion Roc3 (max weight).
You want to do a similar thing as to your midranges. I would start with 2 slowish drivers. I prefer to throw a stable disc such as a Teebird (either star or champion plastic and near max weight) and a less stable disc such as a Valkyrie (again star or champion plastic and near max weight).
That should cover most anything that your midranges can’t and you don’t need maximum distance on.
Next, I would choose a driver that is well within your arm speeds ability to throw. In my experience, most people tend to throw drivers that are well faster than their arm speed can truly handle. I would recommend 3 drivers of the same mold.
For this instance, I will pick an Innova Destroyer as they are discs that have the ability to fly with a great variance of stability. I prefer the star plastic for drivers, but that is up to you.
As discs go, Destroyers are notorious for being unpredictable in their stability off the shelf. This is not a bad thing as they are a great discs for many types of shots. I would find one in a lighter weight (such as 167 grams or so) and use that as my turnover or anhyzer disc. Then, I would find one that is stable, but not a meat hook around 172-174 grams. Next, find one that you can’t turn over on your most powerful flat throw at 174 grams and make that your overstable driver.
For putters, I prefer to putt with a stiff plastic as I feel more confident with that in my hand. No matter what you choose, I would make sure that you have 2 of the same putter, just in case something happens to one of them.
There is not a single correct type to use. I putt with Prodigy PA3 in the 350 plastic, but I also like putting with the stiff 300 plastic. I use putters off the tee for most shots 270 and under when the line permits, as I feel the most comfortable throwing them accurately.
I keep a stable throwing putter at max weight, a straight throwing putter at max weight and a very understable putter at max weight for approach shots and tee shots. I also throw a well seasoned PA1 in 300 plastic as my straight putter, and my understable throwing putter is a well seasoned PA4 in 300 plastic.
If you have all of the discs recommended above, you would be at 15 total in your bag right now. That being said there will be a need for a few utility discs that fill the gap for shots that require a more extreme line.
