Not knowing anything about anything (28 handicap) won't stop me offering my opinion
Putting is hugely personal, and there aren't really any rights and wrongs - try loads, even ones that seem wacky to you, and choose the one that fits your hands. It's not that easy to buy a 'bad' one - it's not like it takes the impact force of most other clubs. What's most important is that it feels comfortable to you.
Remember that you can always think about making your choice, then searching/waiting for one of that model to come up on Ebay, particularly with the better known brands.
