A Buzzz is a great disc but I prefer Rocs. Here is the thing, a casual golfer might prefer a Buzzz only because they are pretty much straight right out of the box. A Roc on the other hand is stable to over stable depending on weight, mold, etc. I carry at least two Rocs during practice rounds and four during tourney's; two 2006 USDGC Champion Rancho Rocs and two 11x Kc Pro Rocs. I am also thinking about the glow Dx. Roc but have not decided yet. Don't get me wrong, I do throw Discraft and Have Used the Wasp, Buzzz, and the Meteor...we're talking mids here but I keep coming back to the Roc. Take a Dx. Roc; When new it will fly like the first Z wasps' used to before the mold change. A Roc that is moderatly broken in will fly like a Buzzz(will left, right or straight depending ong the angle of release), also will tend to turn in a stiff breeze but always dependable. A Beat in Roc is like a Meteor; Straight to flippy at moderate speeds and very controllable. So basically my thoughts are that I like the Wasp, Buzzz, and Meteor but why have them in my bag when I can have pretty much the same mold that does different things. The key word is consistency. Now, about your putts. Stick with a putter. If the putter is hard to learn, learn it. The slower the disc, the lower the margine of error. I hope this helps. Good luck!!!
A KC isnt as stable as even the current run of Z Wasps (yes a few years ago a couple runs were alil flippy for a wasp) And you will never find any roc with the glide of a buzzz or a meteor. It doesnt matter what angle you release a buzzz its gonna hold it, not the best wind disc but thats where a wasp and drone comes in and the best part is that instead of spending months and months getting each of those rocs perfectly broken in only to break it or lose it and have to start all over again, you can go with a discraft mid and grab a new one off the self that will just exactly the same as the one you just lost.
My goal isn't to bash Discraft. It is to help a fellow discgolfer by providing the kind of knowledge I would have liked to have when I started over Nine years ago. I am sorry I upset your apple cart in some way. It wasn't my goal as stated above. In any case, this is simply an example of different opinions based on separate life experiences.
Honestly, I would suggest that you focus on learning to throw your putter further. One of the few bright spots in my otherwise mediocre game is my 50'-150' putter upshots. Past that range, I think that we can all agree that it's not really putting anymore.
P.S. I highly recommend a Nuke to anyone who can throw further than 300' consistently. I watched my best friend add 30'-50' to his throw simply by throwing a Nuke. The ESP ones break in fast, which is great for those of us who don't have a ton of power. Not exactly an easy disc to get the hang of though; I still struggle with my release.
As far as a midrange to throw for long putts...you'll want to get the same putter in a lighter weight or just get a Rattler. You want something that will hold a line with no effort and that will fly straight with ease.
If you don't have the arm to throw ~350 consistently in all conditions throw after throw a Nuke will not be a good choice for you. You'll want to get drivers that are understable to start and then you can move to more stable stuff. The thing to keep in mind is that you want something you can control. Unless you're playing on courses that a lot of the pros play on (and even then) you don't need to throw 450+ feet. If you can learn to drive 300' straight and controlled and be deadly from 200' or less then that is all you need to compete at most any tourney you'll ever go to.
When running a long putt the last thing you want is a disc which glides a long way. You probably want a disc which doesn't glide at all so that when it misses (as most long putts will, even in the most skillful of hands) it stays close. Midrange discs have medium glide. Not the superior glide of a driver or the stunted glide of a putter. So a midrange disc doesn't make a lot of sense for a long putt except for those players who don't use putters at all.
The perfect disc for the long putt/ short run is the Rattler. The Rattler is a putter type disc with no glide and it has the ability to fly straight even if thrown softly. It does, though, require significant skill and touch to master. But since all worthy goals take time to achieve, there is no time like the present to start. If you have an aversion to the Rattler you can create a similar flight by taking a standard putter and breaking it in for many, many years. Then it will be almost as good as a Rattler. :)
The Nuke is a power disc which flies farther than anything else I have ever thrown. The Nuke wants to fly far and fast. If you have the power to use it it may be as magical for you as it is for me.
