I've used Aviars, Blowfly, Wizard, Millenium Omega, Vibram Summit before I've finally settled.
My main putter is a Yeti Pro Aviar. It's an Aviar but made with a R-Pro plastic. During the cooling process it becomes slighlty concave. I use it because for me it feels low profile for a putter, I like how it feels in my hand, I like the plastic, and I've gotten the most consistent with it (for me). I always carry 2. One beat in, one fairly fresh. Beat in one is for tailwinds, or longer puts. I do tend to put with a slightly anhyzer spush (spin push, more spin than push) a la Anthon. I use my fresh one for headwinds or when I need to use more hyzer than anhyzer because of foliage, etc.
I also carry one DX Rhyno for a bit stronger headwinds. It seems funny to me (because I prefer Yetis), but I prefer DX Rhynos over R-Pro Rhynos.
In even stronger headwinds (as seen at GBO), I even putt with a beat in DX Gator. Flat top, terrible glide. Fights wind and then just drops to the ground if you miss.
I recommend finding one you like, then stockpile. Over the last year, I've accumulated through purchase, trade, winnings, etc. 8 Yetis now. Practicing with a stack of the same putter, varrying just 2-3 grams, has helped me the most.
All three are beaded putters. I just prefer beads. Beadless putters seem naked or amputated, or something like that.
