Pros: Good sightlines, great feel off the insert
Cons: Forward press is love-it-or-hate-it
I picked up the Odyssey 2-Ball Backstryke putter from Callaway Preowned about 2 years ago. I had seen them in stores and for some reason they always felt good for me at the time. This was the beginning of my golf career, and I didn't have much experience in golf equipment. I think I got pretty lucky because this has been a good putter to build in good habits for me.
Looking down at the putter, the first thing you'll notice is the unusual shape. Sure, it's a mallet, but the shaft attaches to the head at an unusual location that is presented by Odyssey as being to help promote good sightlines for the ball. Because, they say, the shaft stays out of the way, you can clearly see the ball and the alignment throughout the swing, ostensibly promoting good contact. I certainly haven't seen anything to disprove that. It's really easy to align. I've since tried a number of different putters, and this is really one of the best for me for alignment. The shaft is angled forward, forcing you to use a forward press. That's a matter of preference. I've always liked a forward press, so this felt great to me from the beginning. Others might dislike it. The putter comes with a very thin pistol grip. I've considered a thicker Super Stroke style grip, but I don't think it'd work with the forward press nature of the shaft.
The face of the putter is outstanding. The insert is extremely soft and any ball you play will feel great off the putter face, whether it be a rock hard Top Flite or a Super Soft from Callaway. It's absolutely the star feature of the putter.
I've gone back and forth with this putter over the years. I think if I could do it all over today, I'd go with a different putter, just because I don't think a center-shafted putter fits my swing, but I'm not planning on ditching this anytime soon. The shape is funky and will get some questions from playing partners, but most people I've let try it have really taken to it and liked it. I think it's a putter that makes a great first impression. If you're looking to try something different, it's a solid choice. But definitely try it before you buy it!
