Only adding - sometimes it doesn't hurt to try something different! If it works - stick with it. Once you become a decent green reader, once you develop a consistently good putting pace, it just comes down to your aim and how confident you are.
Not saying technology can't help. But it will not help a lack of confidence on the greens, long term.
I've been making my own putters for years,they are different from anything I've ever seen,
due mainly to the material I use.
Also the head weight can be anything from 200 grms to over 500 grms.
I'm thinking of sending my Cameron's in to be refinished. It's really not much money and they come out great. The more I putt with them, the more I realize I'll just end up using them forever.
Working on one that is truly an original. I mean it's so obvious it should have already been discovered......but NO>>>>>>>>>>>>>>>I guess it's going to take BOM to make it happen.
.....and legal yet! LOL
This one better? 
darpar - do you sell them?
My go to putter is an old Golfsmith Brassmaster 05, which is essentially a Bullseye putter. I regripped it with a jumbo pistol grip turned 90 degrees so the back of my front hand is parallel to the clubface. What this lightweight setup gives me that the high MOI setups do not is a sense of touch. I average almost a full stroke per hole difference between this setup and higher MOI setups.
