The Challenger OS is an amazing putter and a great setup in Discraft’s putter lineup! I putted with Challengers, Roaches, Luna’s and they all flew how I wanted them to, except I wanted a touch more glide and stability and the Challenger OS was perfect! The Crazy Tuff plastic is rock hard and feels perfect in my hands! I also use the Pro-D as well, but I prefer the CT for the slight slickness and feel! The Challenger OS is a very slightly deeper putter, but very comfortable in the hands of you have a medium to larger sized hand! Don’t get me wrong, the Challenger OS is STABLE, but it most definitely isn’t a meathook by any means. I love the Challenger OS for putting primarily and I look forward to using them for throwing and seeing how well the turn out! Overall, I highly recommend the Challenger OS! 

On CT plastic:

The Crazy Tuff plastic feels just as I'd hoped--very KC Pro esque, plenty firm with a texture that's smooth, bordering on slick. Beats in with some small blemishes rather than the deep gouges I've had occur in my Lunas.

On the Challenger OS:

The bead may be barely larger than the microbead on a Challenger. Rather than thinking of this as a Challenger with a larger bead, it might be more accurate to say that it's a Challenger SS with a bead. It's not as OS as I was expecting--nothing like a Breaker. I had previously driven/upshot/putt with BT Hard Shields--the CT Challenger OS feels and flies very similarly. It's stable to the point that it won't flip, but not so OS that it reduces the glide you'd expect from a workhorse putter.
