I think it better in the long run to stick with what gives you the highest level of consistency.
Now I'm not saying don't try things out, but pretty soon you'l realize for yourself what types of putters work best for you.
This comes down to basically 4 types;
Shallow beaded and beadless
Traditional beaded and beadless
Yeah, I know, there are understable, overstable neutral and lots of other little things, but I'm talking about feel and consistency.
For three years, I threw and putted with nothing but Yeti Pro Aviars. I liked how the plastic felt but they were a little deep compared to what I threw before, but I stuck with them. I had enough of buying a new putter every other week because I was having an off day or someone on the forums was suggesting X-Y-Z putter. You can learn an awful lot by sticking with one mold through thick and thin. Last year I switched to Wizards because I wanted a little more stability and I didn't like the feel of KC Pro for putting. So far so good, I no longer have an issues with deep putters, they don't feel awkward at all, but shallow putters? They feel terrible for me.
Pick something and just make the effort to stick with it. When you learn the mold inside and out, you'll have better information at your disposal when and if you decide to make a change. You'll never get that info switching every other week.
