I've used Aviars mostly for the last 18 years or so. When I started playing the only players I knew who didn't putt with Aviars were old guys who still used a lid. I went back and forth between the big bead and the small bead. Finally I decided the big bead was more consistent for putting and drives into a wind and the small bead was better off the tee when you had no wind or a tail wind, so I carry both.
I tried understable putters like the 86 Softie, but they require too much touch. I would overpower them and flip them most of the time, so I gave up and went back to hyzer putting with an overstable putter.
I did putt with Magnets for a couple of years shortly after they came out. I liked Magnets a lot as a putter as they have a nice consistent and dependable fade at low speeds and are great for hyzer putts. They are not as good off the tee IMO, but if you can get some height on your throw they glide out to about the same distance. Eventually (and this is stupid but true) I got so many Aviars in players packs at tournaments that I had over 20 of them, and I only had three or four Magnets. Instead of paying money to get more Magnets, I just went back to Aviars since I had so many of them already. It's a pretty dumb way to pick your putter, but it is what it is.
I had Wizards in my bag most of this summer. If I can keep the nose down and throw the Wizard properly, it will crush an Aviar in distance off the tee. However, I stink and throw nose up all the time. The Aviar is more forgiving if you get the nose up and will still glide out for some decent D. The Wizard will hyzer out short if you get the nose up. The Wizard and big bead Aviar are almost identical when putting.
I have putt with the XD, Omega Supersoft, APX and Warlock for extended periods at some point or another. Each had their pros and cons. The XD has a great feel in the hand, but with all that glide it blows by the basket by a mile if you miss. The APX is like a superstraight Magnet, but the ones I had were made from the Elite Pro plastic and I hated the feel of it. The Omega Supersoft was just to soft for me. The Warlock for me feels and flies EXACTLY like a Wizard. I noticed no difference at all.
Also, I didn't have 20+ of any of those discs either. It's hard to avoid the big stack 'o Aviars.
