I realize it doesnt matter what putter I'm using. I can go with anything stable (Wizards, Warlocks, Ions, Anodes, Aviars, Magnets or whatever) and still be fine. I have a couple warlocks in the bag now - they do the job.
I am a push putter so I find this to generally be true for me as well. But that has not stopped me from settling on a single mold for my putting. For me, challengers are the most comfortable in my hand. It is also the first putter that I encountered 6 years ago. I had a brief love affair with magnets, lasting for about 1 summer, and gave the Ion an honest chance. But the challenger is it for me, I think.
